【问题描述】：
你好 Stackoverflow 朋友，
我需要一个应用程序，使用相机捕获图像并重复显示在图像视图中。拍照后我将这张照片发送到服务器。对于这个过程，我使用名为 myBackgroundUploader 的 AsynTask 类。当我单击按钮时，我调用了 Asysnctask。我完成了，但是在拍摄了 2 三张照片后，我得到了内存不足错误并且我的应用程序强制关闭。我试图回收（），空值但没有用。谁能告诉我如何避免这个错误。这是我得到的日志。
onCreate()
{
setContentView(R.layout.detail_profile);
String fname=new File(getFilesDir(), "MyFile.jpeg").getAbsolutePath();
if(imgView!=null)
{
imgView.destroyDrawingCache();
}
imgView=(ImageView)findViewById(R.id.imageView1);
imgView.setImageURI(Uri.fromFile(new File(fname)));
}
public void onClick(View v) {
if(checkInternetConnection()==false)
{
new AlertDialog.Builder(detailProfile.this).setTitle("Warning!").setMessage("No Internet connection").setIcon(R.drawable.icon).setNeutralButton("Close", null).show();
} if(diTask!=null)
{
AsyncTask.Status diStatus=diTask.getStatu();
if(diStatus!=AsyncTask.Status.FINISHED)
{
return;
}
}
fileprocess();
diTask=new myBackgroundUploader(detailProfile.this);
diTask.execute("url for server");
}
