添加adMobs标语后，应用程序内存不足

Question

我不断收到以下错误：

java.lang.OutOfMemoryError: Failed to allocate a 9961068 byte allocation with 4194304 free bytes and 5MB until OOM

在我的应用程序中，我有2个不同的广告单元，分别用于2个不同的活动。 每个活动都通过按钮相互链接。 但是，当我进入第三个活动时，将弹出上面显示的错误，并且应用程序强制关闭。 在添加广告之前，这没有发生。

试图显示缩放的位图时似乎内存不足，但位图只有488x567px。 我正在使用以下内容来显示其中myPlayer是imageView的图像：

myPlayer.setImageResource(playerTypes[3]);

如何减少应用程序所需的内存？

这是显示的第一个活动的片段：

    AdView mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);


    play.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(getBaseContext(), MainActivity.class);
            startActivity(intent);
        }
    });

这是显示的下一个活动的摘录：

    super.onCreate(savedInstanceState);
    //requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_main);
    MobileAds.initialize(getApplicationContext(), "<ad-unit-id>");
    AdView mAdView = (AdView) findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    mAdView.loadAd(adRequest);

    begin.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View view) {

            if(players.getText().toString().equals("") || getTotalPlayers() == 0){
                Toast.makeText(MainActivity.this, "How many players?", Toast.LENGTH_SHORT).show();
            } else {

                Intent intent = new Intent(getBaseContext(), PlayerAssign.class);
                intent.putExtra("PLAYER_COUNT", "" + getTotalPlayers());

                startActivity(intent);
            }
        }
    });

除了xml文件中设置的背景图像外，以上两个活动都没有任何图像。

下一个活动是发生错误的地方。

show.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            if(!myPlayer.getTag().equals(R.drawable.contenthidden)){
                Toast.makeText(PlayerAssign.this, "Press Next Player", Toast.LENGTH_SHORT).show();
            } else if(numClicked <= numPlayers){
                numClicked++;
                int rand = (int) (Math.random()*100);
                Log.d("rand",""+rand);
                if(rand<25 && numMafia != numMafiaAdded){
                    myPlayer.setImageResource(playerTypes[0]);
                    myPlayer.setTag(playerTypes[0]);
                    numMafiaAdded++;
                }else if (rand<50 && numDoctor != numDoctorAdded){
                    myPlayer.setImageResource(playerTypes[1]);
                    myPlayer.setTag(playerTypes[1]);
                    numDoctorAdded++;
                } else if (rand<75 && numDetective !=numDetectiveAdded){
                    myPlayer.setImageResource(playerTypes[2]);
                    myPlayer.setTag(playerTypes[2]);
                    numDetectiveAdded++;
                }else if (rand<100 && numVillager != numVillagerAdded){
                    myPlayer.setImageResource(playerTypes[3]);
                    myPlayer.setTag(playerTypes[3]);
                    numVillagerAdded++;
                }
            } else {
                myPlayer.setImageResource(R.drawable.setupcomplete);
                myPlayer.setTag(R.drawable.setupcomplete);
            }
        }
    });
