FAQ & Troubleshooting (React Native)

Android

Picture in Picture(PIP) cannot be closed normally when killing the application in Android 11

class MainActivity: ... {

  // ...

  override fun onDestroy() {
    super.onDestroy()
    ...
    
    // Please add this line to your MainActivity
    // We call FireworkSdk.closePip inside FWReactNativeSDK.INSTANCE.closePip
    FWReactNativeSDK.INSTANCE.closePip()
  }
}

Out of JVM Memory

Gradle build daemon has been stopped: JVM garbage collector thrashing and after running out of JVM memory. Add the following configuration to the file: gradle.properties.

...
org.gradle.jvmargs=-Xmx4g

Gradle plugin version is larger than 4.1.x

If your Gradle plugin version is larger than com.android.tools.build:gradle:4.1.x. Please set the compileSdkVersion = 31 and targetSdkVersion = 31 . And add the following configuration to the file: src/main/AndroidManifest.xml .

<manifest>
  ...
  <application>
    ...
    <activity
      android:name=".MainActivity"
      ...
      android:exported="true" // sdk version 31
    >
      ...
    </activity>
  </application>
</manifest>

Use JDK11 and Gradle 7.x.

If you want to use JDK11 and Gradle 7.x. Please do:

1. JAVA_HOME = JDK11 (system env)

2. classpath("com.android.tools.build:gradle:7.x.x") (build.gradle)

3. distributionUrl=https://services.gradle.org/distributions/gradle-7.x-all.zip (gradle-wrapper.properties)

4. And change the following configuration in the file: app/firework.gradle .

android {
  ...
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_11
    targetCompatibility JavaVersion.VERSION_11
  }
  ...
}

minCompileSdk = 31

• If you met the issue like below:

> The minCompileSdk (31) specified in a
        dependency's AAR metadata (META-INF/com/android/build/gradle/aar-metadata.properties)
        is greater than this module's compileSdkVersion (android-30).
        Dependency: androidx.lifecycle:lifecycle-viewmodel-ktx:2.4.0.

Please do:

configurations.all {
  resolutionStrategy {
    ...
    force 'androidx.work:work-runtime-ktx:2.2.0'
    force 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0'
  }
}

Maybe your compileSdkVersion = 30 and targetSdkVersion = 30 , your Gradle is below 6.9-all and the Gradle plugin is com.android.tools.build:gradle:4.1.x .

Okhttp version issue

If you met the issue like below:

/data/app/com.thesouledstore-1b4KZ7kSaE_DlLmco_iLxQ==/base.apk!classes5.dex)
2022-02-25 21:06:33.506 16304-18932/? E/com.newrelic.android: TransactionStateUtil: Attempting to convert network exception java.io.IOException to error code.
2022-02-25 21:06:33.508 16304-18932/? E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher
    Process: com.thesouledstore, PID: 16304
    java.lang.NoSuchMethodError: No static method delimiterOffset(Ljava/lang/String;IILjava/lang/String;)I in class Lokhttp3/internal/Util; or its super classes (declaration of 'okhttp3.internal.Util' appears in /data/app/com.thesouledstore-1b4KZ7kSaE_DlLmco_iLxQ==/base.apk!classes5.dex)

Maybe your okhttp version is 3.x.x . Please do:

Solution: force the version to your app/firework.gradle file, like below:

configurations.all {
  resolutionStrategy {
    ...
    force 'com.squareup.okhttp3:okhttp:3.12.12'
    force 'com.squareup.okhttp3:logging-interceptor:3.12.12'
    force 'com.squareup.okhttp3:okhttp-urlconnection:3.12.12'
  }
}

Glide version issue

Glide issue: if you met the issue like below:

GeneratedAppGlideModuleImpl is implemented incorrectly. 
If you've mannually implemented this class, remove your implementation. 
The Annotation processor will generate a correct implementation.
(FastImageViewManager.java:xxx)

Maybe your react-native-fast-image version is >7.x.x and <8.1.4 . Please do:

Solution 1: add the excludeAppGlideModule = true to your android/build.gradle file, like below:

buildscript {
    ...
    ext {
        excludeAppGlideModule = true
        ...
    }
    ...
}

Solution 2(recommended): upgrade the react-native-fast-image version to >= 8.1.4

Natively started activity is closed when launching RN app from desktop icon on Android

Please do:

1. Remove the android:launchMode="singleTask" from AndroidManifest.xml

2. Build a release APK or build a debug APK with bundleInDebug=true

project.ext.react = [
  bundleInDebug: true,  // just for exporting an apk, if you want link codes to metro(npm start), please change it to false
  // enableHermes: false,  // clean and rebuild if changing
  entryFile: "index.tsx",
]

popNativeContainer vs startFloatingPlayer

1. popNativeContainer is used to close the current full-screen player. We only support using this API when PiP is disabled(enablePictureInPicture is false).

2. startFloatingPlayer is used to make the current full-screen player into the floating player. We only support using this API when PiP is enabled(enablePictureInPicture is true).

Don't use popNativeContainer when PiP is enabled(enablePictureInPicture is true)

If you use popNativeContainer when PiP is enabled(enablePictureInPicture is true), it will cause inconsistent behavior between iOS and Android. This inconsistent behavior is:

1. No effect on iOS

2. The full-screen player is closed on Android

Don't use startFloatingPlayer when PiP is disabled(enablePictureInPicture is false)

If you use startFloatingPlayer when PiP is disabled(enablePictureInPicture is false), it will have no effect on iOS and Android.

How to enable PiP?

The PiP is disabled by default. You can refer to the following links to learn how to enable PiP.
