android - 如何关闭安卓应用程序？

Question

关于这个主题有很多问题，但没有明确的答案。虽然android的内存管理很扎实，但是很多人认为我们不应该kill android应用。我的情况不同。我想要一个关闭应用程序的选项。我发现了以下用于关闭应用程序的代码，但有时它不起作用。当我点击应用程序上的退出按钮时，应用程序似乎只是自行刷新。

主 Activity .java

@Override
    public void onDestroy()
    {
        super.onDestroy();
        /*
         * Notify the system to finalize and collect all objects of the
         * application on exit so that the process running the application can
         * be killed by the system without causing issues. NOTE: If this is set
         * to true then the process will not be killed until all of its threads
         * have closed.
         */
        System.runFinalizersOnExit(true);

        /*
        * Force the system to close the application down completely instead of
        * retaining it in the background. The process that runs the application
        * will be killed. The application will be completely created as a new
        * application in a new process if the user starts the application
        * again.
        */
        System.exit(0);
    }

@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
switch(item.getItemId()) {
   case R.id.close:
                Intent intentFinish = new Intent(this, FinishActivity.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(intentFinish);
                finish();
                return true;
}
return super.onMenuItemSelected(featureId, item);
}

FinishActivity.java

package com.mypackage;

import android.app.Activity;
import android.os.Bundle;

public class FinishActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        finish();
    }
}

我也试过 Process.killProcess(Process.myPid()); 但它不起作用。

我找到了我的解决方案。使用它来关闭应用程序

Intent homeIntent = new Intent(Intent.ACTION_MAIN);
homeIntent.addCategory( Intent.CATEGORY_HOME );
homeIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(homeIntent);
