Android ANR Multithreading - android

So I'm working on a project which needs to cut up a video into multiple frames, and save them as Bitmaps on the device.
I'm using FFmpegMediaMetadataRetriever.getFrameAtTime() to obtain the individual frames, which is working, but is slow. To speed it up a bit I'm trying to implement multiple worker threads which go off and grab the frames, finally responding back to UI via an anonymous function.
I have a class MyVideoProcessor which handles the video processing, and this is called from my EditVideoActivity.
The threads start, and start processing, but shortly afterwards the EditVideoActivity dies (ANR).
From what I can see, there is nothing running on UI (apart from at the very end (which I confirm only runs once)) so not sure why the UI thread is being held up by the worker threads.
EDIT:
So I've switched out FFmpegMediaMetadataRetriever for the standard MediaMetadataRetriever and everything works. BUT I need to use FFmpegMediaMetadataRetriever, as the OPTION_CLOSEST in MMR doesn't work as it should.

how to track percentage of progressing download of each downloading file in exoplayer library?

I am working on a media player app. I'm using ExoPlayer library. I have a playlist of videos, and I want to download videos simultaneously. I done it by using available demo app of exoplayer library on GitHub. I want to show progress of each downloading in the UI. For this job I get help from DownloadNotificationUtil.buildProgressNotification method.
#Override
protected Notification getForegroundNotification(TaskState[] taskStates) {
float totalPercentage = 0;
int downloadTaskCount = 0;
boolean allDownloadPercentagesUnknown = true;
boolean haveDownloadedBytes = false;
boolean haveDownloadTasks = false;
boolean haveRemoveTasks = false;
Log.e(TAG,"size task state: "+taskStates.length);
for (TaskState taskState : taskStates) {
Log.e(TAG,"taskId= "+taskState.taskId);
if (taskState.state != TaskState.STATE_STARTED
&& taskState.state != TaskState.STATE_COMPLETED) {
continue;
}
if (taskState.action.isRemoveAction) {
haveRemoveTasks = true;
continue;
}
haveDownloadTasks = true;
if (taskState.downloadPercentage != C.PERCENTAGE_UNSET) {
allDownloadPercentagesUnknown = false;
totalPercentage += taskState.downloadPercentage;
}
haveDownloadedBytes |= taskState.downloadedBytes > 0;
downloadTaskCount++;
}
int progress = 0;
boolean indeterminate = true;
if (haveDownloadTasks) {
progress = (int) (totalPercentage / downloadTaskCount);
indeterminate = allDownloadPercentagesUnknown && haveDownloadedBytes;
Log.e(TAG,"notifi "+progress);
}
return DownloadNotificationUtil.buildProgressNotification(
this,
R.drawable.exo_icon_play,
DOWNLOAD_CHANNEL_ID,
null,
null,
taskStates);
}
Now,I can track the progress downloading. But I still have a problem. I can't understand which item is downloading to update it's progress bar in the UI. Is there a Identical id of each download to recognize it? For example Android Download Manager has a download ID for each downloading file. But I don't know , how to handle this problem.
This is MediaDownloadService:
public class MediaDownloadService extends DownloadService {
public static String TAG="MediaDownloadService";
private static final int FOREGROUND_NOTIFICATION_ID = 1;

}

return ((MyApplication) getApplication()).getDownloadManager();
}
#Nullable
#Override

return null;
}
#Override

float totalPercentage = 0;
int downloadTaskCount = 0;
boolean allDownloadPercentagesUnknown = true;
boolean haveDownloadedBytes = false;
boolean haveDownloadTasks = false;
boolean haveRemoveTasks = false;
for (TaskState taskState : taskStates) {
if (taskState.state != TaskState.STATE_STARTED
&& taskState.state != TaskState.STATE_COMPLETED) {
continue;
}
if (taskState.action.isRemoveAction) {
haveRemoveTasks = true;
continue;
}
haveDownloadTasks = true;
if (taskState.downloadPercentage != C.PERCENTAGE_UNSET) {
allDownloadPercentagesUnknown = false;
totalPercentage += taskState.downloadPercentage;
}
haveDownloadedBytes |= taskState.downloadedBytes > 0;
downloadTaskCount++;
}
int progress = 0;
boolean indeterminate = true;
if (haveDownloadTasks) {
progress = (int) (totalPercentage / downloadTaskCount);
indeterminate = allDownloadPercentagesUnknown && haveDownloadedBytes;
Log.e(TAG,"notifi "+progress);
sendIntent(progress);
}
return DownloadNotificationUtil.buildProgressNotification(
this,
R.drawable.exo_icon_play,

null,
null,
taskStates);
}
private void sendIntent(int progress){
Intent intent = new Intent(ConstantUtil.MESSAGE_PROGRESS);
intent.putExtra("progress",progress);
LocalBroadcastManager.getInstance(MediaDownloadService.this).sendBroadcast(intent);
}
#Override

return;
}

In the getForegroundNotification() method, you will get list of TaskState objects, which has a members downloadPercentage and your download Uri taskState.action.uri which is unique for each download task. Store these variables into a map and broadcast the map.
override fun getForegroundNotification(taskStates: Array<TaskState>): Notification {
var totalPercentage = 0f
var downloadTaskCount = 0
var progressMap : HashMap<Uri, Int> = HashMap()
for (taskState in taskStates) {
if (taskState.state != TaskState.STATE_STARTED && taskState.state != TaskState.STATE_COMPLETED) {
continue
}
if (taskState.action.isRemoveAction) {
continue
}
if (taskState.downloadPercentage != C.PERCENTAGE_UNSET.toFloat()) {
totalPercentage += taskState.downloadPercentage
progressMap.put(taskState.action.uri, taskState.downloadPercentage.toInt())
}
downloadTaskCount++
}
var progress = 0
progress = (totalPercentage / downloadTaskCount).toInt()
broadcastIndividualProgress(progressMap)
return buildProgressNotification(progress)

Data gets loaded from MainActivity, the saved data is passed on to other activities as a parcellable bundle via intent, the passed data is displayed in DetailActivity but not in ReviewActivity.
Alternatively, if I can load reviews alongside YouTube keys from DetailActivity, I believe I can handle the database issue from there, but two Loaders wouldn't just work together, the app crashes; I am aware two AsyncTasks concurrently run together solved this problem, but I prefer to use Loaders because of performance on configuration change

I had to play and pause the Gif image Glide - Cannot stop gif onClick- Getting TransitionDrawable instead of Animate/GifDrawable
The idea is to get drawable from view,checking if it is an instance of Gifdrawable and playing and pausing it.(Hoping the gif image is already playing)
Add this In OnClick of GifImageView
Drawable drawable = ((ImageView) v).getDrawable();
if (drawable instanceof GifDrawable) {
GifDrawable animatable = (GifDrawable) drawable;
if (animatable.isRunning()) {
animatable.stop();
} else {
animatable.start();
}
}
I found the solution of above problem using GifMovieView!!!
GifMovieViewer.java
public class GifMovieViewer extends Activity {
private Button btnStart;
private GifMovieView gif1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gif_movie_viewer);
gif1 = (GifMovieView) findViewById(R.id.gif1);
btnStart = (Button) findViewById(R.id.btnStart);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
gif1.setMovieResource(R.drawable.earth_tilt_animation);
//for pause
// gif1.setPaused(gif1.isPaused());
}
});
}
public void onGifClick(View v) {
GifMovieView gif = (GifMovieView) v;
gif.setPaused(!gif.isPaused());
}
}

How to wait for an activity to finish in asynctask

I know that the purpose of the AsyncTask is to run asynchronously with other tasks of the app and finish in the background, but apparently I need to do this, I need to start an activity from AsyncTask and since I cant extend an activity in this class I can not use startactivityforresult, so how can I wait till my activity finishes?
Here is my code:
public class ListSpdFiles extends AsyncTask<Void, Void, String[]> {
public AsyncResponse delegate = null;
private static final String TAG = "ListSpdFiles: ";
Context applicationContext;
ContentResolver spdappliationcontext;
public final CountDownLatch setSignal= new CountDownLatch(1);
