创建新版本时启动后崩溃

Question

我在真实设备和模拟器上启动了 Android TV 应用程序，但没有收到任何错误

当我发布新版本并收到“启动后崩溃”消息时，我多次修复它并收到相同的消息和拒绝状态。

这是来自goolge的邮件内容，我不知道如何解决！

 `App Status: Rejected Your app has been rejected and wasn't published due to the policy issue(s) listed below.

我编写了一个类来将错误消息记录到远程，但 crashHanlder 没有被命中

I put crashHandler code in launcher activity
public class TvActivity extends FragmentActivity {
   protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tv);

    
    Thread.setDefaultUncaughtExceptionHandler(new CrashHandler());

...do stuff
    }
}
 

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);

        // Inject some info about android version and the device, since google can't provide them in the developer console
        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);
    }
}

Answer 1

按照你的方法

public class TvActivity extends FragmentActivity {
   protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tv);

    
    Thread.setDefaultUncaughtExceptionHandler(new CrashHandler());

...do stuff
    }
}

您正在呼叫

Thread.setDefaultUncaughtExceptionHandler(new CrashHandler())

。

所以，了解顺序..

首先会调用

new CrashHandler()

。 在该构造函数中，您正在调用

this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler()

。 但是，请注意，

Thread.setDefaultUncaught...()

尚未被调用，其参数仍在构建中以供调用。因此，

defaultUEH

不会被设置为

CrashHandler

的实例。它可能仍然是

null

或之前设置为默认值的其他处理程序的实例。

然后一个

CrashHandler

实例将返回给调用者。

Thread.setDefaultUncaught...(ch)

将在创建这个新实例时被调用。

在此之后，

Thread.getDefaultUncaught...

将返回正确的值。

尝试在 TvActivity.onCreate() 方法中这样做：

CrashHandler ch = new CrashHandler();
Thread.setDefaultUncaughtExceptionHandler(ch);
ch.setDefaultUEH();  // New method which will get the default UEH set by above statement

在CrashHandler类中添加一个新方法：

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

并且构造函数

public CrashHandler() {}

不必在那里。其中唯一的语句应该被删除。整个构造函数本身可以删除，因为它将是没有任何逻辑的默认构造函数。
