使用自定义 UncaughtExceptionHandler 升级 Firebase Crashlytics

Question

在工作时Update your apps to use latest Firebase Crashlytics SDKs before November 15, 2020，在我激活自定义后UncaughtExceptionHandler，它不会再向 Crashlytics 发送崩溃。

下面的代码我将其设置onCreate()在Application.

        FirebaseCrashlytics crashlytics = FirebaseCrashlytics.getInstance();
        crashlytics.setCrashlyticsCollectionEnabled(!BuildConfig.DEBUG); // only release able to send.
        crashlytics.sendUnsentReports(); // send reports
        Thread.setDefaultUncaughtExceptionHandler((t, e) -> {
            FirebaseCrashlytics.getInstance().recordException(e); // record exception.
            // below things are restart app when crash appeared.
            PackageManager packageManager = getPackageManager();
            Intent intent = packageManager.getLaunchIntentForPackage(getPackageName());
            if (intent != null) {
                ComponentName componentName = intent.getComponent();
                Intent mainIntent = Intent.makeRestartActivityTask(componentName);
                startActivity(mainIntent);
                Runtime.getRuntime().exit(0);
            }
        });

当我删除 custom 时UncaughtExceptionHandler，它能够向 Crashlytics 报告。

使用 Fabric 库时，下面的代码可以完美运行。（/sf/answers/3448641241/）

        CrashlyticsCore core = new CrashlyticsCore.Builder()
                .disabled(BuildConfig.DEBUG)
                .build();
        Fabric.with(new Fabric.Builder(this).kits(new Crashlytics.Builder()
                .core(core).build()).initializationCallback(new InitializationCallback<Fabric>() {
            @Override
            public void success(Fabric fabric) {
                Thread.setDefaultUncaughtExceptionHandler((t, e) -> {
                    LogWrapper.logException(e);
                    PackageManager packageManager = getPackageManager();
                    Intent intent = packageManager.getLaunchIntentForPackage(getPackageName());
                    if (intent != null) {
                        ComponentName componentName = intent.getComponent();
                        Intent mainIntent = Intent.makeRestartActivityTask(componentName);
                        startActivity(mainIntent);
                        Runtime.getRuntime().exit(0);
                    }
                });
            }

            @Override
            public void failure(Exception e) {
                e.printStackTrace();
            }
        }).build());

对此有什么解决办法吗？任何帮助将不胜感激。非常感谢。

解决方案发布在这里。我将把修改后的代码粘贴到这里，供任何寻找它的人使用：

下面的代码是用Java编写的。对于 Kotlin，请访问原始帖子。

public class NewCrashHandlerContentProvider extends ContentProvider {
    public static final String TAG = "NewCrashHandler";
    static long PRE_DELAY_MILLIS = 3000L;
    static long POST_DELAY_MILLIS = 3000L;

    public static void initializeAfterFirebaseContentProvider() {
        Thread.setDefaultUncaughtExceptionHandler(new PreFirebaseCrashHandler(Thread.getDefaultUncaughtExceptionHandler()));
    }

    @Override
    public boolean onCreate() {
        try {
            Log.i(TAG, "+onCreate()");
            Thread.setDefaultUncaughtExceptionHandler(new PostFirebaseCrashHandler(Thread.getDefaultUncaughtExceptionHandler()));
            return true;
        }finally {
            Log.i(TAG, "-onCreate()");
        }
    }

    @Nullable
    @Override
    public Cursor query(@NonNull Uri uri, @Nullable String[] projection, @Nullable String selection, @Nullable String[] selectionArgs, @Nullable String sortOrder) {
        return null;
    }

    @Nullable
    @Override
    public String getType(@NonNull Uri uri) {
        return null;
    }

    @Nullable
    @Override
    public Uri insert(@NonNull Uri uri, @Nullable ContentValues values) {
        return null;
    }

    @Override
    public int delete(@NonNull Uri uri, @Nullable String selection, @Nullable String[] selectionArgs) {
        return 0;
    }

    @Override
    public int update(@NonNull Uri uri, @Nullable ContentValues values, @Nullable String selection, @Nullable String[] selectionArgs) {
        return 0;
    }


    static class PreFirebaseCrashHandler implements Thread.UncaughtExceptionHandler {
        Thread.UncaughtExceptionHandler previousUncaughtExceptionHandler;
        public static final String TAG = "PreFirebaseCrashHandler";

        public PreFirebaseCrashHandler(Thread.UncaughtExceptionHandler previousUncaughtExceptionHandler) {
            this.previousUncaughtExceptionHandler = previousUncaughtExceptionHandler;
        }

        @Override
        public void uncaughtException(@NonNull Thread t, @NonNull Throwable e) {
            LogWrapper.logException(e);
            try {
                // my own logic
                Thread.sleep(PRE_DELAY_MILLIS);
            }catch (Throwable throwable) {
                LogWrapper.e(TAG, throwable.getLocalizedMessage());
            } finally {
                previousUncaughtExceptionHandler.uncaughtException(t,e);
            }
        }
    }

    static class PostFirebaseCrashHandler implements Thread.UncaughtExceptionHandler {
        Thread.UncaughtExceptionHandler previousUncaughtExceptionHandler;
        public static final String TAG = "PostFirebaseCrashHandler";

        public PostFirebaseCrashHandler(Thread.UncaughtExceptionHandler previousUncaughtExceptionHandler) {
            this.previousUncaughtExceptionHandler = previousUncaughtExceptionHandler;
        }

        @Override
        public void uncaughtException(@NonNull Thread t, @NonNull Throwable e) {
            LogWrapper.e(TAG, "+uncaughtException($thread, $throwable)");
            try {
                Thread.sleep(POST_DELAY_MILLIS);
            }catch (Throwable throwable) {
                LogWrapper.e(TAG, throwable.getLocalizedMessage());
            }finally {
                previousUncaughtExceptionHandler.uncaughtException(t,e);
            }
            LogWrapper.e(TAG, e.getLocalizedMessage());
        }
    }

}

在Application文件中写入onCreate()方法：

NewCrashHandlerContentProvider.initializeAfterFirebaseContentProvider();

也别忘了更新manifests

<provider
            android:authorities="${applicationId}"
            android:name=".utils.NewCrashHandlerContentProvider"
            android:exported="false"
            android:initOrder="101"
            android:grantUriPermissions="false"/>
