如何杀死的Onne单一的点击整个应用程序..完成（）不工作？它重定向到塔previous活动...请指引我。

 公共无效的onClick（查看为arg0）{
            // TODO自动生成方法存根
            WallpaperManager WP = WallpaperManager
                    .getInstance（getApplicationContext（））;

            尝试 {
                显示D =（（窗口管理器）getSystemService（Context.WINDOW_SERVICE））
                        .getDefaultDisplay（）;
                INT宽度= d.getWidth（）;
                INT高= d.getHeight（）;
                wp.​​setBitmap（B1）;
            }赶上（IOException异常E）{
                Log.e（错误，无法设置图片作为壁纸，E）;
            }

                        完（）;

        }
 

解决方案

System.exit（）的不杀你的应用程序，如果你有一个以上的活动在堆栈上

使用 android.os.Process.killProcess（android.os.Process.myPid（））; 这样

样品

 公共无效onBack pressed（）{
    android.os.Process.killProcess（android.os.Process.myPid（））;
    super.onBack pressed（）;
}

How to kill whole application in onne single click.. finish() is not working?? it redirects to tha previous activity...pls guide me.

          public void onClick(View arg0) {
            // TODO Auto-generated method stub
            WallpaperManager wp = WallpaperManager
                    .getInstance(getApplicationContext());

            try {
                Display d = ((WindowManager) getSystemService(Context.WINDOW_SERVICE))
                        .getDefaultDisplay();
                int width = d.getWidth();
                int height = d.getHeight();
                wp.setBitmap(b1);
            } catch (IOException e) {
                Log.e("error", "Cannot set image as wallpaper", e);
            }

                        finish();

        }

System.exit() does not kill your app if you have more than one activity on the stack

Use android.os.Process.killProcess(android.os.Process.myPid()); this way.

for sample

public void onBackPressed() {
    android.os.Process.killProcess(android.os.Process.myPid());
    super.onBackPressed();
}

I hope this will help you.
