Question

我的应用程序崩溃，在日志中我看到了这一点，我试图找到我如何解决它，但只有我发现这是因为一个上下文和一个人使用YourActivityName.this并且它工作正常，但我喜欢这个我的应用程序崩溃了

这是日志：

Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@482fc81 is not valid; is your activity running?

这是代码：

 protected void runServices() {
        if (LocationUtil.isLocationEnabled(getBaseContext())) {
            if (checkPermission()) {
                runLocationService();
            }
        } else {
            AlertDialog.Builder dialog = new AlertDialog.Builder(this);
            dialog.setMessage(getResources().getString(R.string.location_settings_disabled));
            dialog.setPositiveButton(getString(R.string.go_to_location_settings), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                    App.getBus().post(new PageNavigateEvent(Const.APP_SETTINGS_LOCATION));
                }
            });
            dialog.setNegativeButton(getResources().getString(R.string.cancel), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                    finish();
                }
            });
            dialog.show();
        }
        runTrackerService();
        runConfigService();
    }

并且此行导致错误：

dialog.show();

添加当前 ActivityName.this ，而不是 this 。

 AlertDialog.Builder dialog = new AlertDialog.Builder(YourCurrentActivityName.this);

Java android android.view.WindowManager $ BadTokenException：无法添加窗口
