NoSuchMethodError for com/google/android/exoplayer2/upstream/DefaultAllocator

问题

I am using

com.amazon.android:exoplayer-ui:r2.5.4

in my project I just upgraded IDE to Android Studio 3.3.1. in my build.gradle I have below code for compile

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7
}

While trying to build, I get this error:

Task :app:mergeExtDexDebug FAILED AGPBI: {"kind":"error","text":"Default interface methods are only supported starting with Android N (--min-api 24): void com.google.android.exoplayer2.Player$EventListener.onLoadingChanged(boolean)","sources":[{}],"tool":"D8"}

FAILURE: Build failed with an exception.

• What went wrong: Could not resolve all files for configuration ':app:debugRuntimeClasspath'. Failed to transform file 'classes.jar' to match attributes {artifactType=android-dex, dexing-is-debuggable=true, dexing-min-sdk=21} using transform DexingTransform Error while dexing.

When I change the sourceCompatibility and targetCompatibility to JavaVersion.VERSION_1_8, it gets build successfully but the app crashes with following error:

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.mypackage, PID: 4374 java.lang.NoSuchMethodError: No direct method (Lcom/google/android/exoplayer2/upstream/DefaultAllocator;IIJJLcom/google/android/exoplayer2/util/PriorityTaskManager;)V in class Lcom/google/android/exoplayer2/DefaultLoadControl; or its super classes (declaration of 'com.google.android.exoplayer2.DefaultLoadControl' appears in /data/app/mypackagename/base.apk:classes5.dex)

Any suggestions?

Add below code in app level build.gradle

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

upgrade your SDK and associated lib to 28...Also upgrade your Gradle to gradle-4.10.1-all.zip...then rebuild app...then Invalidate Cache/Restart from File menu.

If still not working then add below code and follow steps of rebuild and Invalidate Cache/Restart

implementation ('react-native-track-player') {
    exclude group: 'com.google.android.exoplayer'
}
implementation 'com.google.android.exoplayer:exoplayer:2.7.3'
