android-file | android SD卡文件操作，文件信息，获取Office格式（Word，Excel，PPT，PDF）的文件并打开 | Document Editor library

I am trying to open the pdf file which I downloaded & saved in external storage. But When I open my app its gets crashed and showing following error;

I'm creating an application in Ionic in which I want to add the functionality of reading files from external storage devices that are connected to the mobile through micro USB (on Android devices) or Lightning (on iPhones).

After researching about it; I didn't find something that is already built apart from the File plugin which has a great API for read/write access on the mobile itself and the sdcard that is mounted on the device, but I haven't been able to read the USB flash stick that is connected on the mobile.

At the moment I'm testing on an Android device with the below code

Before asking this question I searched for an answer

In short: problem appears with the latest version of Gradle plugin for Android Studio version 3.0.0.

If I use previous version of Gradle plugin (2.3.3) Studio builds .apk without problem/

Error text:

Error:Execution failed for task ':stockManagment:transformClassesWithStackFramesFixerForNextDebug'.

All solutions found at SO and other sites recommend using 'exclude', but these problems usually appear with 'META-INF/somefile.txt' , not 'META-INF/' directory itself.

I can't exclude whole 'META-INF/' directory, but I exclude common files inside this dir (licence, dependencies, etc.).

Here are my build.gradle files.

In my Android app, I need to load a text file from the storage using a file chooser dialog. Some time ago, I followed the instructions in this Android file chooser topic (original answer).

On the phone with Android 4.2.2 (API 17) everything works fine. This code (actually as the uri.getPath() itself) returns the real path of the file:

I have an Android app with multiple flavors, each flavor defines the app_name string on its own strings.xml file. Recently I incorporated a new library that defines its own value for app_name at its own strings.xml file. The problem is that the final value for app_name in the merged resources is the app_name value defined by the library. How I can bring priority to the flavor app_name value?

Currently I'm define specific values for app_name in the individual strings.xml file per flavor.

I expect that the app_name value was the flavor value and not the library value.

UPDATE: My flavors are defined as below:

I use this code in my app/build.gradle.

Context: I am developing hybrid app with Cordova 6 and SAPUI5 Framework (for now only need to worry about Android).

What I want: Copy/move a file to a path fast. Maybe getting a FileEntry from a File/Blob object from a FileUploader on sapui5.

Input: FileUploader

Output: File Object So I get the file when I select it by doing the following:

I followed this to Capture Images and Upload from Web-view

So here It's working fine in Portrait Mode

But Its not working or Web-view Reloading In two cases 1. When I rotate the Phone 2. When I capture the Image (In some Phone) By default Camera is landscape so its reloading .. but in some other phones its working but in Portrait only..

For fixing reload web-view I have give this in normal

I'm trying to listen to any event in external storage directory, i.e. file added, removed or modified through Android FileObserver but its onEvent method never gets called.

I've tried all of the following solutions:

Android FileObserver [duplicate]

FileObserver instance is being garbage collected

How do you implement a FileObserver from an Android Service

And as for my code, its given below:
