項(xiàng)目需求：
點(diǎn)擊圖標(biāo)有界面，自動運(yùn)行或者開發(fā)點(diǎn)擊運(yùn)行項(xiàng)目無界面

這個需求困擾了我很久椅野，2天多吧 后來換了一個思路就實(shí)現(xiàn)了

效果圖：

就是弄個全局變量，在就是開啟一個服務(wù)里去賦值就行...
我之前想的是怎么獲取APP圖標(biāo)籍胯，在去監(jiān)聽這個圖標(biāo)的事件竟闪，在給全局變量賦值，之后再依據(jù)全局變量去判斷杖狼。

代碼如下

package com.test.testdemo;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (!Config.runFlag){
            Log.i("TAG", "自動或者點(diǎn)擊運(yùn)行無界面---- ");
            Intent intent = new Intent(this, TestService.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startService(intent);
            finish();
        }
    }
}
