本文介绍了为什么我的应用程序使用所有内存并得到 OutOfMemoryError: Failed to allocation?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
为什么总是这样?我什至没有位图可以回收，我不知道为什么我的应用程序会抛出内存错误.
why this happeing all the time?i dont have even a bitmap to recycle and i dont know why my application throw memory error.
我从图库中选择图像这里是从图库中获取图像然后将其显示在某些 imageView 上的代码.
i select image from gallery here is the code to get an image from gallery then show it on some imageView.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
ImageView b = (ImageView) findViewById(R.id.viewImage);
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
File f = new File(Environment.getExternalStorageDirectory().toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(f.getAbsolutePath(),
bitmapOptions);
b.setImageBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
f.delete();
OutputStream outFile = null;
File file = new File(path, String.valueOf(System.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == 2) {
Uri selectedImage = data.getData();
String[] filePath = { MediaStore.Images.Media.DATA };
Cursor c = getContentResolver().query(selectedImage,filePath, null, null, null);
c.moveToFirst();
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
Log.w("path of image from gallery......******************.........", picturePath+"");
b.setImageBitmap(thumbnail);
b.setTag(picturePath);
}
}
}
之后，用户图片下方有 3 个图片按钮(从图库中挑选).当用户按下它们中的每一个时，将获得可绘制的 imageView 的名称并将其发送到另一个活动然后我想在该 Imagebutton 上为用户图像添加水印并显示在一个 imageView 中
after that there is 3 imagebuttons below user image(which picked from gallery). when user press on each one of them will get the name of that imageView drawable and will send to another activity then i want to watermark user image on that Imagebutton and show in one imageView
private static HashMap<Integer,String> activityMap = new HashMap<Integer,String>();
static {
activityMap.put( R.id.agahi1,"agahi1");
activityMap.put( R.id.agahi2,"agahi2");
}
// use this in the layout xml file for all the buttons onClick attribute
public void Clicked( View vw ) {
String a = String.valueOf(activityMap.get(vw.getId()));
Intent i = new Intent(this,fotCreator.class);
ImageView b = (ImageView) findViewById(R.id.viewImage);
String c = (String) b.getTag();
i.putExtra("image",c);
i.putExtra("frame",a);
startActivity(i);
}
这是水印活动的代码
package net.svncorp.shadikade;
import android.content.Intent;
import android.content.res.Resources;
import android.graphics.drawable.Drawable;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ImageView;
import android.widget.ProgressBar;
public class fotCreator extends ActionBarActivity {
private AsyncCaller myasync;
private ProgressBar bar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fot_creator);
//progress bar
bar = (ProgressBar) this.findViewById(R.id.progressBar);
MainActivity.checkversion(this);
}
@Override
public void onBackPressed() {
super.onBackPressed();
this.finish();
}
@Override
protected void onResume() {
super.onResume();
myasync = new AsyncCaller();
myasync.execute();
}
private class AsyncCaller extends AsyncTask<Void, Void, Drawable>
{
@Override
protected void onPreExecute() {
super.onPreExecute();
bar.setVisibility(View.VISIBLE);
}
@Override
protected Drawable doInBackground(Void... params) {
try { // simulate here the slow activity
Intent intent = getIntent();
final String frame = intent.getStringExtra("frame");
String image = intent.getStringExtra("image");
Resources resources = getResources();
int id = resources.getIdentifier(frame, "drawable", getPackageName());
Drawable d = resources.getDrawable(id);
return d;
} catch (Exception e1) {
e1.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Drawable result) {
super.onPostExecute(result);
//this method will be running on UI thread
ImageView finalimage = (ImageView)findViewById(R.id.finalimage);
if (isCancelled() || result == null) {
return;
}
finalimage.setImageDrawable(result);
bar.setVisibility(View.GONE);
}
}
@Override
protected void onPause() {
super.onPause();
myasync.cancel(true);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_fot_creator, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
现在这段代码在按下图像按钮 2 或 3 次并转到水印活动时工作得如此之快，但它变得越来越慢，有时它在模拟器中冻结，我在 logcat 中看到这些
now this code works so fast for 2 or 3 times of pressing imagebuttons and go to watermarker activty but its keep getting slower and slower and sometimes it freeze in emulator and i see these in logcat

我认为这是许多像我一样的人的问题...任何帮助将不胜感激.
i think this is the problem of many others like me... Any help will be appreciated.
推荐答案
也许在 Manifest 的应用程序标签中添加这一行会对您有所帮助；
Maybe adding this line in Manifest on application tags will help you;
<application
...
...
android:largeHeap="true" >
......
......
</application>
