kandi X-RAY | apkfile Summary
ApkFile is a library which creates a representation of an APK composed of Java objects which can be easily inspected for analysis or serialized into JSON. The goal of the library is to provide a robust way to inspect hostile malware samples, but it's general purpose enough to be used for other stuff too. This library and APKiD provide the machine learning feature extraction for Judge, an Android malware detection engine.

QUESTION
For context, I'm trying to create an Android app in Java that can share itself to other phones. I managed to get the app to successfully send its own APK to another android phone using bluetooth (see implementation below).
The problem is that the APK from one phone will not install on another phone. To troubleshoot, I downloaded a third-party APK extractor to send my app across with the same results - the APK is successfully transferred but won't install on the other phone. I then tried to use the APK extractor to share a random selection of Google Play apps, some apps would successfully install on the second phone, others wouldn't.
At this stage, I'm quiet sure this is a compatibility issue. How could I make my APK be more compatible across devices? For reference, I'm currently testing it on 3 phones: Samsung Galaxy S7, Huawei Nova 3i and Motorolla XT1052, but ultimately I want the app to be accessible on as many devices as possible.
Thanks in advance :)

Answered 2021-Jul-26 at 06:00Found out the problem! I was sending across the debug APK, not the release APK. I just created a signed APK in Android studio (Build>Generate Signed Bundle/APK). I didn't come up with the solution myself, however the answerer removed their answer before I could select it.

I'm trying to build an Android pipeline in Azure Devops for my Xamarin application. This is what I have so far:
...ANSWER
Answered 2021-Jun-18 at 18:51The csproj file was set to create an AAB file instead of an APK file. I overrode this behavior specifically for our Azure pipeline by adding the arg, -p:AndroidPackageFormat=apk, to the Xamarin Android build command.
QUESTION
I am trying to set up a build pipeline for the Xamarin Android app using AzureDevops Pipeline.
The step that is causing my hair to go thin and grey is Signing and Zipaligning.
For signing, I have created a self-signed key using:
keytool -genkeypair -v -keystore keystore.keystore -alias keyAlias -keyalg RSA -keysize 2048 -validity 10000
Then I have added keystore.keystore to azureDevOps secure files location and enabled it for all pipelines
I then set the signing step in the following way:

Answered 2021-Apr-15 at 14:07The cause was a lack of internal mental capacity as usual. I didn't set the output dir. After changing apkFiles: '**/*.apk' to apkFiles: '$(outputDirectory)/*.apk' it all worked.
QUESTION
I have a variable containing some basic aidl code (basically just a bunch of method signatures). And I would like to echo that variable in a way that syntax highlighting is added to it. For example to display method names, data types and parameter names in different colors.
I know it can be done by hand like this:
...ANSWER
Answered 2021-Mar-21 at 13:48I'm asking for a solution to a problem
Steps:
- Write a parser for the syntax you want to parse. Preferably in real programming language, like python or C++. Tokenize input and detect token types (function return type, function identifier, parameters types, parameter identifiers, etc.).
- Apply specific colors to specific tokens types.
- Output.
I can't think of a reasonable way to implement this in Bash.
I can't think either, I believe because there are none reasonable ways to do it in bash. Bash is a shell, it's not a full easy to use programming language, it's not fast, it's a shell meant primarily to run other programs. Consider a different language. You could aim for awk, but I would go with python.
For simple cases you may write it in regex ex. in sed or awk (still - not bash) and tokenize input with some regexes, apply colors and output, but I do not believe you'll be able to handle ex. function pointers in C++.
Sample tokenizer written in sed, just for funzies:
QUESTION
I am really struggling with some variables which I have in my variable group named 'android-pipeline'. Inside this variable group, I have some variables with values. But when I am running the pipeline it cannot read the values inside my variable group. :(
Example: Inside the variable group, I have a variable called $(key.alias) I am trying to get this value which is behind the variable, see my code below.
I think something is wrong with the syntax (or the way I am using it), but I cannot find the right syntax for using my $(key.alias) variable.
Also, inside the variable group I have made sure that All pipelines have access to this Variable group. Can someone, please tell me how I can get the value behind the $(key.alias) variable and use this in a task? I tried to follow many guides, but none are clear enough for me or not working

QUESTION
For context, I am trying to use an Azure build pipeline to build multiple flavors of an Android app. Each flavor has its own separate signing keystore, and all of those keystores are stored in my 'secure files' in the library.
However, when I try to dereference the $(Keystore) variable during the 'android signing' task, it doesn't seem to recognize that that is a variable that exists, and tries instead to locate a file called '$(Keystore)'
Am I doing something wrong here? This seems like it should work.
A sanitized example looks like this:

Answered 2021-Feb-16 at 21:11You're missing the step to download the Secure File. Unlike variable groups, you need to explicitly download them to have access via the secure file name.
You'll want to add something similar to the example task below to your steps to pull the secure file. Then, you'll access your secure file via NAME_PARAMETER.secureFilePath:

I'm setting up a build pipeline for a Xamarin Android app. I've got all the steps running that pull, restore, and build the project into an APK file. My next step is to sign the package before publishing.
What I have so far:
- A .keystore file was created and uploaded to the Pipelines > Library > Secure Files. I verified that this file is being located correctly by providing an incorrect name and observing the results, then putting the correct name in.
- Passwords are stored as secured variables in the pipeline itself.
- File name and aliases are stored as variables on the pipeline file itself.

QUESTION
I'm not sure what happened, everything used to build just fine with our pipeline in Azure Devops.
But just recently, we have every build failing at zipaligning ... the APK zipaligns and builds just fine when using the Android Studio IDE, but it fails in Azure Devops pipeline.
Here is the start of the zipalign from Azure:
...ANSWER
Answered 2020-Nov-23 at 17:26So after going back and forth with some on the github azure pipelines task issue thread, I found that by changing my Android gradle plugin from 4.1.0+ (it was at 4.1.1) to 4.0.0 in my project level gradle.settings, the azure pipeline build would complete successfully.
Gradle itself stayed at version 6.5, but the Android gradle plugin was set to 4.0.0 to make it build successfully.
Then, another pointed this thread out on the Google issue tracker: https://issuetracker.google.com/issues/162117652
It appears that the zipalign is no longer necessary as of the latest Android gradle plugin 4.1.0+. I guess Android gradle plugin 4.1.0+ already zipaligns the apk, so any subsequent call to zipalign will show a failure as it's already zipaligned.
So the ultimate solution here, was to keep the latest version of Android gradle plugin (4.1.1) and change zipalign: true to zipalign: false in my Azure pipeline AndroidSigning@3 task.
You can check to confirm if your APK is actually zipaligned, even with the zipalign set to false in the pipeline, by running the following:

...ANSWER
Answered 2020-Aug-06 at 13:13Just use mExampleList.clear() at the first line of your parseJSON() function and then you'll be able to add the "updated" items.
In addition I'd suggest that you move swipeRefreshLayout.setRefreshing(false) to the end of Volley onResponse and onError() implementation - Right now you're telling the swipeRefreshLayout to stop refreshing before the request(that happens asynchronously) has finished
