为什么我的应用程序使用所有内存并获取OutOfMemoryError:分配失败？
为什么我的应用程序使用所有内存并获取OutOfMemoryError:分配失败？
提问于 2014-11-25 07:11:59
为什么总是这样?我甚至没有可回收的位图，我也不知道为什么我的应用程序抛出内存错误。
我从图库中选择图像这里是从图库中获取图像，然后将其显示在一些imageView上的代码。
@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);
}
}
}在这之后，在用户图片下面有3个图片按钮(选自图库)。当用户按下他们中的每一个将得到该imageView可绘制的名称，并将发送到另一个活动，然后我想要水印用户图像在该图像按钮和显示在一个imageView中
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和转到水印活动的两三次后运行得如此之快，但是它变得越来越慢，有时它在模拟器中冻结，我在logcat中看到了这些。

也许在Manifest的应用程序标签上添加这一行会对你有所帮助；
<application
...
...
android:largeHeap="true" >
......

在Android5上也有类似的问题。将你的图片移到/drawable-nodpi而不是/drawable

如果您正在使用Emulator进行测试，请尝试将虚拟设备的Ram设置为2 2gb左右。我在虚拟设备上遇到了同样的问题，但程序在我的物理android设备上运行得很流畅
