QUESTION

INSTALL_PARSE_FAILED_MANIFEST_MALFORMED error

Asked 2022-Apr-09 at 18:01

Good day,

After installing Android Studio Bumblebee 2021.1.1 Patch 3 and importing my older project (then updating gradle, sdk, and dependancies), I started struggling with INSTALL_PARSE_FAILED_MANIFEST_MALFORMED error. I have followed the suggestions in Installation error: INSTALL_PARSE_FAILED_MANIFEST_MALFORMED? without luck.

Things I checked:

Package name is lowercase
Exported field is explicitly defined

Last item that I believe is responsible for this error is in Logcat: Could not get package user id: run-as: unknown package: com.test.app

How can I resolve this issue?

Manifest:

 <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"

ANSWER

Answered 2022-Apr-09 at 18:01

As with error description in error, it's about LeakLauncherActivity

leakcanary.internal.activity.LeakLauncherActivity: Targeting S+ (version 31 and above) requires that an explicit value for android:exported be defined when intent filters are present

And it looks like this issue has been fixed in new version of leak canary lib. https://github.com/square/leakcanary/issues/2076

ANSWER

Answered 2022-Mar-30 at 08:08

Your libraries are defining probably an "intent_filter" on an activity

debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.5.4'
releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.5.4'

If your application is targeting API 31+, the attribute "exported" is mandatory.

So as the developer of that library didn't target API 31, the exported flag what not mandatory on his side. And he built it without exported attribute.

So what you can do, is redefine that specific class on your manifest to declare it explicitly exported or not. For example :

<activity android:name="com.squareup.leakcanary.internal.DisplayLeakActivity"
         android:exported="true"/>

Answered 2021-Oct-05 at 10:38

After the build has failed go to AndroidManifest.xml and in the bottom click merged manifest see which activities which have intent-filter but don't have exported=true attribute. Or you can just get the activities which are giving error.

Add these activities to your App manifest with android:exported="true" and app tools:node="merge" this will add exported attribute to the activities giving error.

Example:

      <activity
            android:name="<activity which is giving error>"
            android:exported="true"
            tools:node="merge" />

You will have to do this once, you can remove this once the library developers update their libs.

I got the same crash log because I enabled:

minifyEnabled

in debug mode. The solution is adding:

-keep class androidx.appcompat.view.WindowCallbackWrapper { *; }
-keep class android.support.v7.view.WindowCallbackWrapper { *; }

in your progurd rules.

The solution turns out that I need to downgrade the libraries I used the 1.3.1 version instead of 1.4.1 for the androidx.appcompat library , the version 2.15.1 instead of 2.16.1 for the com.google.android.exoplayer and the version 2.1.1 instead of 2.1.3 for the androidx.constraintlayout

QUESTION

RxJava Single - Getting a memory leak, how to correctly unsubscribe?

Asked 2022-Jan-30 at 12:31

I'm using RxJava's Single.fromCallable() to wrap around a third party library that makes an API call. I was testing different states on the call, success, failed, low network, no network.

But on the no network test I ran into a memory leak for the first time ever using RxJava. I spent the last hour combing through the code and trying to narrow down the leak with the LeakCanary library.

I figured out it was coming from subscribing to the Single.fromCallable().

Single.fromCallable(() -> {
       return remoteRepository.makeTransaction(signedTransaction).execute();
})
       .subscribeOn(Schedulers.newThread())
       .observeOn(AndroidSchedulers.mainThread())
       .subscribe(txHash -> {
              Log.d(TAG, "makeTransaction: " + txHash);
                    
                   
       }, err -> {
             Log.e(TAG, "makeTransaction: ", err);
                    
       });

Once I remove the

.subscribe(txHash -> { ... });

It no longer leaks.

I've tried googling stackoverflow with RxJava Single unsubscribe and I'm getting answers saying that you don't need to unsubscribe from Single

https://stackoverflow.com/a/43332198/11110509.

But if I don't I'll be getting memory leaks.

I've tried to unsubscribe by making the Single call an instance variable in my ViewModel:

Disposable mDisposable;

mDisposable = Single.fromCallable(() -> {...}).subscribe(txHash -> {..});

and unsubscribing it in the Fragment's onDestroy() method so it will unsubscribe if the user exits the screen before the call is finished.

@Override
    public void onDestroy() {
        super.onDestroy();
        mViewModel.getDisposable().dispose();
    }

But it's still leaking. I'm not sure if this is the correct way to unsubscribe or maybe I'm doing something else incorrectly.

How can I correctly unsubscribe from the Single Callable?

Edit:_________________________________

How I'm recreating the issue:

Screen one is launches screen two. The call is performed instantly on the creation of screen two. Since I'm testing it with no network, the query is continuing to perform on screen two until it times out. So closing the screen two before the call finishes causes the leak.

It doesn't seem to be a context leak because I've removed tried testing it by removing all the methods inside the .subscribe():

Single.fromCallable(() -> {
           
            return remoteRepository.makeTransaction(signedTransaction).execute();
})
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(txHash-> {
              //Removed all methods here.
              //Still leaks.

         }, err -> {

                    
         });

But when I remove:

.subscribe(txHash-> {
                   
}, err -> {  
              
});

it no longer leaks.

ANSWER

Answered 2022-Jan-30 at 12:31

One easy mistake to be made in Java is forgetting about the implicit reference to the outer class instance whenever you instantiate an anonymous class in a non-static context.

For example:

Single.fromCallable(() -> {
   // some logic
   return 5;
});

Is actually the same as:

Single.fromCallable(new Callable<Integer>() {
                @Override
                public Integer call() throws Exception {
                    // some logic
                    return 5;
                }
            });

So what you did is instantiate a new instance of the anonymous class which implements the Callable interface.

Now, let's put this in some context.

Let's assume we have this inside a service class:


class SomeService {
    int aNumber = 5;
    Single<Integer> doLogic() {
        return Single.fromCallable(() -> {
            // using "aNumber" here implicates Service.this.aNumber
            // e.g. writing "return 5 + aNumber" is actually the same as
            return 5 + SomeService.this.aNumber;
        });
    }
}

Most of the time this isn't an issue because the outer classes outlive the short-lived objects instantiated inside the methods. However, if your instantiated object can outlive the outer object (in your case the Single is still running even after the ViewModel is out of scope), the whole outer object (in your case, the ViewModel) remains in memory as the Callable still has the implicit reference to it.

There are many ways how to get rid of this unwanted reference - the easiest being instantiating the object in a static context where you capture only what you really need (instead of the whole "outer this").


class SomeService {
    int aNumber = 5;
    
    static Callable staticCallableThatCapturesOnlyParameters(int param) {
        return () -> {
            // outer this is not available here
            return 5 + param; // param is captured through the function args
        };
    }
    Single<Integer> doLogic() {
        return Single.fromCallable(staticCallableThatCapturesOnlyParameters(aNumber));
    }
}

Another approach would be to simply avoid the anonymous object altogether and use static inner classes, but that quickly bloats code.

Check all the data members of your Activity there is some data member which is outliving your activity's lifecycle.

Also check in what places you are passing the activity context and MainActivity.this instance.

Lastly check what callbacks / lambda's are associated with this activity there could be a case that one of your class's member is being shared with some other class like a recycler view adapter which could lead to a leak.

As a thumb rule when working on memory leak issues I encapsulate most if not all data passing with WeakReference that way you are both safe from NPE plus you get benefit of a decoupled class.

Edit - As shared in the comment below using weak reference is a bad practice and there are better ways to resolve memory leaks. Kindly check the answer from @Pierre or link to the comment posted below.

After Kotlin 1.6 and Android Studio update, databinding shows errors but app compiles and runs fine

Asked 2021-Dec-23 at 09:48

My android studio version is

Arctic Fox | 2020.3.1 Patch 3
Build #AI-203.7717.56.2031.7784292, built on October 1, 2021

After updating IDE and kotlin to 1.6, I opened a project I was working on and Android Stidio marked data binding fields as red, showing the following error:

enter image description here

In text:

Cannot access 'androidx.databinding.Observable' which is a supertype of 
'com.cioccarellia.wordbucket.databinding.ActivityMainBinding'. 
Check your module classpath for missing or conflicting dependencies

The weird thing is that everything compiles and the app works just fine, these errors are just in the IDE, and they pop up every time I access views through data binding.

I haven't changed my dependencies since updating android studio. Anyone else has the same problem / solution for this situation?

The Main Activity xml:

Try to restart the IDE. If that does not work, clean the project be going to Build > Clean Project at the top of the window, then completely rebuild it by going to Build > Rebuild Project.

Edit: Another reason is that Android Studio will no longer support binding to straight elements, so you have have to specify the binding yourself.

To do this, add BuildFeatures in the application gradle file:

android {
compileSdk 31

//This right here
buildFeatures{
    viewBinding true
}

defaultConfig {
    applicationId "com.cioccarellia.wordbucket"
    minSdk 23
    targetSdk 31

    versionCode 1
    versionName "1.0.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary true
}

Then create a new binding by adding this to your activity file:

//Declare the binding
private lateinit val binding : ActivityMainBinding

override fun onCreate(savedInstanceState: Bundle?) {
    //Initialize the binding
    binding = ActivityMainBinding.inflate(layoutInflater)

    super.onCreate(savedInstanceState)
    //Change the content view to the root of the binding
    setContentView(binding.root)
}

Then reference binding when using your views:

binding.toolbar.title = bucket.name

QUESTION

Activity leaked after orientation change after using AndroidX Navigation Compose

Asked 2021-Nov-13 at 10:45

The MainActivity gets leaked after the second time the orientation changes, but only after navigating to a new destination using the navHostController.

A working project where this can be reproduced is available here.

These are the reproduction steps:

Run the app (it will load the FooScreen, that only contains a TopAppBar and a Button).
Click the "Open Bar screen" Button (it will load the BarScreen, that only contains a TopAppBar)
Change the orientation of the device from portrait to landscape
Change the orientation back to portrait

At this point you should see StrictMode complaining about the leak inside the logcat:

2021-11-02 16:23:20.672 31230-31230/com.leinardi.template E/StrictMode: class com.leinardi.template.ui.MainActivity; instances=2; limit=1

Things I have noticed:

the leak happens only after the 2nd change of orientation (so, if you start with the phone in portrait, when you go back from landscape to portrait)
the leak happens also on the Debug screen, if I navigate to it using the nav component
the leak does not happen if the Bar screen is accessed via deep link (adb shell am start -d "template://bar" -a android.intent.action.VIEW)
the leak does not happen if use the navigate up button of the top app bar to go back from Bar screen to Foo screen (Foo screen never leaks)
reproducible on API level 24, 28 and 30 (I did not test on other levels)

Things I've already tried:

Remove the instance of the nav host from the activity (lateinit var navHostController: NavHostController)
Use rememberCoroutineScope() instead of LaunchedEffect() for the templateNavigator.destinations.collect {} (MainActivity.kt:71)

I've also tried to use the Android Studio Profiled to investigate the leak, but I wasn't really successful. Here some screehsots:

I have the suspect that this could be a bug of some AndroidX library, but maybe I'm just doing something wrong.

The repro project is not exactly streamlined: it's a multi module single activity MVVM-MVI Compose only template project that I'm building. Is not done yet but most of the things should be in place.

This is the overview of the modules:

In short, the App only has the single Activity with no logic beside setting up the nav host. The navigation logic is inside the core-navigation. Each feature module provides UI and business logic. Currently there are 3 features with 1 screen each: Foo, Bar and Debug. Foo screen has only one button that leads to Bar screen. The leak happens inside Bar screen, if you rotate the device twice. It does not happen if you access Bar via Deeplink.

The leak is actually a bug in the navigation compose library and a fix will be available with the next release: https://issuetracker.google.com/issues/204905432#comment4
