Android 捕获错误和用户信息

我有一个问题，因为我的应用程序在后台运行，有时会出现关闭它的错误。如何捕获任何活动或服务中的错误，以便播放声音并在通知栏上添加信息？

要解决此问题，您可以使用uncaughtExceptionHandler接口

public class ExceptionHandler implements UncaughtExceptionHandler{

Utils utils ;
Context context;
private final String LINE_SEPARATOR = "\n";

public ExceptionHandler(Context con) {
    // TODO Auto-generated constructor stub
    context = con;
}

@Override
public void uncaughtException(Thread arg0, Throwable arg1) {
    // TODO Auto-generated method stub

    StringWriter stackTrace = new StringWriter();
    arg1.printStackTrace(new PrintWriter(stackTrace));
    StringBuilder errorReport = new StringBuilder();
    errorReport.append("************ CAUSE OF ERROR ************\n\n");
    errorReport.append(stackTrace.toString());

    errorReport.append("\n************ DEVICE INFORMATION ***********\n");
    errorReport.append("Brand: ");
    errorReport.append(Build.BRAND);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Device: ");
    errorReport.append(Build.DEVICE);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Model: ");
    errorReport.append(Build.MODEL);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Id: ");
    errorReport.append(Build.ID);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Product: ");
    errorReport.append(Build.PRODUCT);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("\n************ FIRMWARE ************\n");
    errorReport.append("SDK: ");
    errorReport.append(Build.VERSION.SDK);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Release: ");
    errorReport.append(Build.VERSION.RELEASE);
    errorReport.append(LINE_SEPARATOR);
    errorReport.append("Incremental: ");
    errorReport.append(Build.VERSION.INCREMENTAL);
    errorReport.append(LINE_SEPARATOR);


    //after this you can do whatever you want , like i start an activity and show error log there


 Intent i = new Intent(context,ExceptionActivity.class);
        i.putExtra("exception",errorReport.toString());
        context.startActivity(i);


        android.os.Process.killProcess(android.os.Process.myPid());
        System.exit(10);





    }
    }

再加上这一行

Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler(this));

在每个活动中（未捕获异常可能引发的地方）

在Oncreate方法中使用未捕获异常处理程序

Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread thread, Throwable ex) {
                ex.printStackTrace();
                Log.e(TAG, "Uncaught Exception "+ex);
                            //Habdle your exception here. 

                System.exit(2);
                android.os.Process.killProcess(android.os.Process.myPid()); 
            }
        });

没有代码和/或logcat？？为这种情况创建Try catch。请将代码包装在Try{}块中，然后在catch块上处理错误
