Android 12 Splash Screen API兼容问题：部分低版本设备闪屏后出白屏

我实现了一个独立的SplashScreen Activity，在该页面中执行一次性的全局API调用、SDK初始化、Firebase RemoteConfig默认值配置以及页面路由逻辑。该功能在部分设备上运行正常，但在部分设备上显示闪屏后会出现白屏现象。

测试设备列表 #

1. Samsung S20 FE（Android 12）- 运行正常
2. OnePlus（Android 11）- 运行正常
3. MI（Android 11）- 出现白屏
4. Moto G5 Plus（Android 8）- 出现白屏

注：上述业务逻辑处理耗时较短，日志如下：

Manifest文件配置 #

<activity
    android:name=".splashscreen.SplashScreenActivity"
    android:exported="true"
    android:label="@string/app_name"
    android:theme="@style/Theme.App.Starting">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

values/styles配置 #

<style name="Theme.App.Starting" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">@color/white</item>
    <item name="windowSplashScreenAnimatedIcon">@drawable/ic_impact</item>
    <item name="windowSplashScreenAnimationDuration">500</item>
    <item name="postSplashScreenTheme">@style/AppTheme</item>
</style>

values/styles (v31)配置 #

<style name="Theme.App.Starting" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">@color/white</item>
    <item name="windowSplashScreenAnimatedIcon">@drawable/ic_impact_anim</item>
    <item name="windowSplashScreenAnimationDuration">1000</item>
    <item name="postSplashScreenTheme">@style/AppTheme</item>
</style>

SplashScreenActivity核心代码 #

@Override
protected void onCreate(Bundle savedInstanceState) {
    SplashScreen splashScreen = SplashScreen.installSplashScreen(this);
    super.onCreate(savedInstanceState);
    splashScreen.setKeepOnScreenCondition(() -> true);
    Utils.initThirdPartySdk();
    initiateRemoteConfig();
}

// 最后调用nextScreen()
private void nextScreen() {
    Timber.v("nextScreen");
    boolean userLogin = MainApplication.isUserLoggedIn();
    if (userLogin) {
        Timber.v("User details is not null in SplashScreen");
        showMainActivity();
    } else {
        Timber.w("User details is null in SplashScreen, opening LoginActivity");
        showLoginActivity();
    }
    finish();
}

private void showMainActivity() {
    Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    startActivity(intent);
}
