运行几次后android内存异常

Question

我写了一个包含很多活动的应用。 在我运行大约30次（使用数据库IO，设置图像等3个活动）之后，它将崩溃并且logCat说“在1036340字节分配时内存不足。”

我不知道哪个对象没有从内存中释放......

有谁可以告诉我可能的原因和解决方案？

或者我怎样才能看到内存中的内容？

P.S。我的Bitmap事物在另一个活动中是静态的，所以它不会每次都创建。

致user1779222：    我认为它可能是这个问题的解决方案，所以我试着让它静止。但似乎没有帮助。

致Maharith Aditya S S：----------这是我的logcat ---------------

我使用Bitmap为一些ImageView和其他人使用.setBackgroundResource（Resource）。

我的跑步步骤是：activityA-＆gt;（A finish（））activityB-＆gt;（B finish（））activityC-＆gt;（C finish（））activityA .........

我不知道这些信息是否会有所帮助，我找到了一种观看Heap的方法， 看来“数据对象”可能是问题......

分配跟踪器数量保持在512左右

系统信息/ memery用法未知从3/4增加到

Rahul Kumar：

settingImg() {
  if(something){
      bmp = BitmapFactory.decodeResource(getBaseContext().getResources(),R.drawable.img1);
      img.setBitmap(Bitmap.createScaledBitmap(bmp, scaledwidth, scaledhight, false));
  }else if(something2){
      bmp = BitmapFactory.decodeResource(getBaseContext().getResources(),R.drawable.img2);
      img.setBitmap(Bitmap.createScaledBitmap(bmp, scaledwidth, scaledhight, false));
  }.........
}
swichActivity(){
  Intent intent = new Intent();
  intent.setClass(B.this, C.class);
  intent .setFlags(intent .getFlags() | intent.FLAG_ACTIVITY_NO_HISTORY);
  startActivity(intent);
  bmp.recycle();
  bmp=null;
  finish();


}

我的图像尺寸= 506 * 506 90.9KB

EDIT3

我刚刚编写了一个只有2个Activity和2layout的应用程序，每个只有1个TextView。 内存使用量仍然在增加，但很长一段时间后，内存使用情况仍在缓慢下降。

为什么????

使用Picasso或Glide加载图片，它会为您处理内存。还会调整大小以使位图大小适合您的ImageView。
