Play the ToneGenerator cause ANR

When click the dialerpad, play the ToneGenerator, but cause ANR。
The log:

You can check the code: DialpadFragment.java--ToneGenerator:
private void playTone(int tone, int durationMs)
private void stopTone()
The ToneGenerator stop timed out cause the ANR. But what did ToneGenerator cause to stop timed out? How to analyze and fix this issue?

you can simply use and its work for me
ToneGenerator toneG = new ToneGenerator(AudioManager.STREAM_ALARM, 100);
toneG.startTone(ToneGenerator.TONE_CDMA_ALERT_CALL_GUARD, 200);

Nougat Music audio volume gets dropped suddenly with "Google quick search bar APP"

In my device which is on Android N (7.1.2),Music Player (Play Music application) Volume suddenly goes down if "Google quick search bar APP" is Launched and Volume comes back to normal as soon as we minimizes the Google quick search bar application
tried to put and debug with logs in below files but didnt get the root cause
frameworks/base/media/java/android/media/AudioManager.java
frameworks/base/services/core/java/com/android/server/audio/AudioService.java
Any advise how the Music Volume Fades in and Fades out ?

When you play audio on an Android device the application has to request audio focus. The operating system has different ways of dealing with a conflict in audio focus, it either performs audio ducking, stops the audio briefly, or completely hands over control to another application that requests focus:
From Managing audio focus Android documentation:
Two or more Android apps can play audio to the same output stream
simultaneously. The system mixes everything together. While this is
technically impressive, it can be very aggravating to a user. To avoid
every music app playing at the same time, Android introduces the idea
of audio focus. Only one app can hold audio focus at a time.
TL;DR: It sounds to me like the Google Search bar is requesting audio focus, perhaps for voice control, and the OS is ducking your application audio briefly during this action - after which audio focus is handed back to your application.
See Managing audio focus for more detail.

Android microphone input fails while in bluetooth on some devices

I'm working on doing voice recognition using the device microphone while connected to a bluetooth speaker. This works in most cases, but in a few devices I'm getting some failures.
After a few days of debugging, the best I can find is the following log difference:

It looks to me like its failing to open an input stream off of the mic. I can't find much information on this, but I think it's probably something to do with how i'm using audio focus. Anyone have any insights?

Webview - Window already focused, ignored focus gain

My application has Vimeo HTML5WebView integrated. The video is working fine, when it is portrait mode(on all devices), but when the orientation is changed to landscape, the video starts to flicker.This is happening in tablets - in 7 and 10 inch tablets. When the video flickers, I get a warning in the logcat saying, the window already focused, ignored focus gain.Please refer to the logcat below.
I tried looking at various questions on StackOverflow, but couldn't get a decent solution.

Please let me know, if the webview code helps, and I will add it to my question. From the questions that I have seen on StackOverflow, I feel, this might be a configuration issue, and in my code for webview, I have overwritten, onConfigurationChanged() and also included, android:configChanges to WebViewActivity.
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}
<activity android:name=".WebViewActivity"
android:configChanges="keyboardHidden|orientation|screenSize"/>
Thanks for your help!!!

By placing
android:configChanges="orientation"
for your activity, you are indicating to the system that your activity will handle the orientation change. But you are not really doing anything because all you are doing is:
super.onConfigurationChanged(newConfig);
So, how to solve your issue?
You said you are having the issue when orientation changes occur only on large screens (tablets) and esp. when changing from portrait to landscape. Yo don't see the issue when orientation changes occur on phone devices.
It makes me think that the video quality might not be of good enough quality to be played in landscape mode. Is that true? i.e if you start your activity in the landscape mode initially, do you still see the flickering?
Are you sure it's not a device specific issue? i.e does this issue you described occur on all large screen devices or just one that you are testing?
You have said you are using Vimeo HTML5WebView to render the video. Have you tried on a regular WebView that the platform provides and does similar issues happen with the framework provided widget as well?
Last but not least, you can always save the state of the player (like the timestamp where the video is before orientation) and then use that state to restore your webview after orientation changes. To do that, stop handling configuration yourself and then follow the guidelines mentioned in Saving Activity State and Handling configuration changes and Handling Runtime Changes. If you are absolutely convinced you can handle config changes yourself, then go ahead and do it but don't just call super and expect the system to magically handle the activities object states for you.
Hope this helps.

Best solution every one does is during changes between modes landscape to portrait or portrait to landscape pause the video and leave foucus of webview ie set focus false to webview and after complete restore of the webview gain the focus and play the video. offcouse u need to do some extra java script coding and javascript bridge coding but solution will work.
