Include .aar Library Module Logs Into Android Application File Logger?

Is it possible to access log messages from 3rd party library aar modules somehow and append them when writing a customized file logger? My purpose with the file logger is to be abl

Solution 1:

Why don't you use the logcat command to retrieve logs ?

Here is an example to send logs by email

publicstaticvoidsendLog(Context context) {
       try {
           StringfileName="logcat_" + System.currentTimeMillis() + ".txt";
           FileoutputFile=newFile(context.getExternalCacheDir(), fileName);

           @SuppressWarnings("unused")Processprocess= Runtime.getRuntime().exec("logcat -v time -f " + outputFile.getAbsolutePath());

           IntentemailIntent=newIntent(Intent.ACTION_SEND);
           emailIntent.setType("plain/text");
           emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Android Log");
           emailIntent.putExtra(Intent.EXTRA_TEXT, "See attached log file");
           emailIntent.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(context, "com.yourapplicationid.fileprovider", outputFile));
           context.startActivity(Intent.createChooser(emailIntent , "Send email..."));
       } catch (Exception e) {
           Log.e(TAG, "Exception when sending log: " + e.getMessage());
       }
   }

You need to specify a FileProvider in your Manifest :

<providerandroid:name="android.support.v4.content.FileProvider"android:authorities="com.yourapplicationid.fileprovider"android:enabled="true"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" /></provider>

And the XML file path

<paths><external-cache-pathname="external_cache"path="." /></paths>
