Android TV应用发布后启动崩溃遭拒，CrashHandler未触发求助

问题背景 #

• 本地真机和模拟器测试Android TV应用时无任何报错，但发布新版本后收到Google「启动后崩溃」的拒审提示，多次修复仍未通过
• 自定义的CrashHandler类未触发，无法远程获取崩溃日志

启动Activity代码 #

// CrashHandler代码放在启动Activity中
public class TvActivity extends FragmentActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tv);

        Thread.setDefaultUncaughtExceptionHandler(new CrashHandler());

        // ...其他业务代码
    }
}

CrashHandler类实现代码 #

public class CrashHandler implements UncaughtExceptionHandler {

    private static final String TAG = "CrashHandler";
    private boolean _enableRemoteLog = true;

    private UncaughtExceptionHandler defaultUEH;

    public CrashHandler() {
        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    }

    @Override
    public void uncaughtException(Thread thread, Throwable ex) {
        final Writer result = new StringWriter();
        final PrintWriter printWriter = new PrintWriter(result);

        // 注入设备和系统版本信息，补充开发者控制台缺失的内容
        StackTraceElement[] trace = ex.getStackTrace();
        StackTraceElement[] trace2 = new StackTraceElement[trace.length + 3];
        System.arraycopy(trace, 0, trace2, 0, trace.length);
        trace2[trace.length + 0] = new StackTraceElement("Android", "MODEL", android.os.Build.MODEL, -1);
        trace2[trace.length + 1] = new StackTraceElement("Android", "VERSION", android.os.Build.VERSION.RELEASE, -1);
        trace2[trace.length + 2] = new StackTraceElement("Android", "FINGERPRINT", android.os.Build.FINGERPRINT, -1);
        ex.setStackTrace(trace2);

        ex.printStackTrace(printWriter);
        String stacktrace = result.toString();
        printWriter.close();
        Log.e(TAG, stacktrace);

        if (_enableRemoteLog) {
            remoteLog(stacktrace);
        }

        defaultUEH.uncaughtException(thread, ex);
    }

    private void remoteLog(String content) {
        String url = "https://xxx/log?msg=" + content;
        LogHelper loader = new LogHelper();
        String[] args = new String[2];
        args[0] = url;
        args[1] = "90";
        loader.execute(args);
        Log.d(TAG, "remoteLog: " + content);
    }
}

Manifest中Activity配置 #

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="xxxx">
    <activity
        android:name=".ui.TvActivity"
        android:theme="@style/LightBgBrowse"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <action android:name="android.intent.action.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION"/>
            <action android:name="android.intent.action.ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION"/>
            <category android:name="android.intent.category.LEANBACK_LAUNCHER" />
        </intent-filter>
    </activity>
</manifest>

需要排查的问题 #

1. 为什么应用在Google测试环境中启动后崩溃，但本地测试无问题？
2. 自定义的CrashHandler为什么没有触发，无法捕获崩溃日志？
