android - 当 Activity 从崩溃中重新启动时捕获

Question

您好，我正在处理一个有时有问题并导致 Activity 重启的第 3 方库。有没有办法判断 Activity 何时从崩溃中重新启动？我试过像这样使用未捕获的异常处理程序，但它没有被触发。

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
        @Override
        public void uncaughtException(Thread thread, Throwable throwable) {
            Log.d("un", "caught");
        }
    });

Answer 1

这样写

Thread.setDefaultUncaughtExceptionHandler(new MyExceptionHandler(this,YOURCURRENTCLASSNAME.class));

亲爱的，请使用这个类(class)。我也用过这个

public class MyExceptionHandler implements
        java.lang.Thread.UncaughtExceptionHandler {
    private final Context myContext;
    private final Class<?> myActivityClass;

    public MyExceptionHandler(Context context, Class<?> c) {

        myContext = context;
        myActivityClass = c;
    }

    public void uncaughtException(Thread thread, Throwable exception) {

        StringWriter stackTrace = new StringWriter();
        exception.printStackTrace(new PrintWriter(stackTrace));
        System.err.println(stackTrace);// You can use LogCat too
        Intent intent = new Intent(myContext, myActivityClass);
        String s = stackTrace.toString();
        // you can use this String to know what caused the exception and in
        // which Activity
        intent.putExtra("uncaughtException",
                "Exception is: " + stackTrace.toString());
        intent.putExtra("stacktrace", s);
        myContext.startActivity(intent);
        // for restarting the Activity
//      Process.killProcess(Process.myPid());
        System.out.println("comingggggggggggggggggg in crashhhhhhhhhhhhhhhhhhhh and restrttttttttttttt autometically ");
        Intent i = myContext.getPackageManager().getLaunchIntentForPackage(myContext.getPackageName() );
        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        i.addCategory(Intent.CATEGORY_HOME);
        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        myContext.startActivity(i);
        System.exit(0);
    }
}
