Error inflating class com.google.android.exoplayer2.ui.SimpleExoPlayerView

One Strange thing: the code is working fine while using emulator, but crashes while running building an unsigned apk.

when connected to android studio, it gives the following error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.tv2z.demo/com.tv2z.demo.DemoActivity}: android.view.InflateException: Binary XML file line #32: Binary XML file line #32: Error inflating class com.google.android.exoplayer2.ui.SimpleExoPlayerView

Seems it's a known issue, which the docs say you should use this (found solution here) :

compileOptions {
    targetCompatibility JavaVersion.VERSION_1_8
}

I've tested it now, and it seems to work fine with newest version of ExoPlayer.

Try changing your XML file from:

<com.google.android.exoplayer2.ui.SimpleExoPlayerView
android:id="@+id/exo_player_view"
android:focusable="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/resolution_textView"
android:layout_marginTop="2dp" />

to:

<com.google.android.exoplayer2.ui.PlayerView
android:id="@+id/exo_player_view"
android:focusable="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/resolution_textView"
android:layout_marginTop="2dp" />

Then in your DemoActivity change:

private SimpleExoPlayerView playerView;

to:

private PlayerView playerView;

Also, make sure that your casting is correct:

playerView = (PlayerView) findViewById(R.id.exo_player_view);

Note that I'm using version 2.7.3:

compile 'com.google.android.exoplayer:exoplayer:2.7.3'
