如何为应用程序增加内存？

E/GraphicsJNI(305): VM won't let us allocate 5529600 bytes

我有这个错误，我正在尝试申请

largeHeap="true"

但是我收到了一个错误：

error: No resource identifier found for attribute 'largeHeap' in package 'android'

我的代码：

public class FourthActivity extends Activity {
    ImageView fotik , cig, zajigalka, fotki, btn, string, flash, telefon;
    Animation textfade, buttonfade, fotikfade, sright, sdown, fl, stringfade, fotofade;

public RelativeLayout lay;
@Override

    super.onCreate(savedInstanceState);


    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,  
    WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.fourthlayout);

    ActivitySwipeDetector activitySwipeDetector = new ActivitySwipeDetector(this);
    lay = (RelativeLayout)this.findViewById(R.id.lay);
    lay.setOnTouchListener(activitySwipeDetector);

     fotik.startAnimation(fotikfade);
        fotik.setVisibility(View.VISIBLE);

Answer 1

您是否已将<application android:largeHeap="true" ...>定义为清单中应用程序的属性？至少，您应该使用Honeycomb作为属性。

看一下帖子：https://stackoverflow.com/a/11275719/411951

Answer 2

在清单中，将此代码写入应用程序标记

<application android:icon="@drawable/icon" 
 android:label="@string/app_name" 
 android:largeHeap="true">

largeHeap属性仅在API 11或更高版本之后出现

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

在清单中使用此密码将目标设置为API 19

我希望这可以帮到你
