Image is not displayed in the imageview on giving the path of that image

I am trying to display image on ImageView. I have the image in /storage/sdcard/DCIM/Camera/SAMPLE IMAGES/xxx.png I have used the following code to display image on the ImageView.

/* for(int i =1;i<=info.getrowcount();i++)
{
java.lang.String[] images_paths = {};
images_paths[i-1]=info.fetchsingles(i);

}*/
hi.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(MainActivity.this,newlist.class);
startActivity(i);

// Inflate the menu; this adds items to the action bar if it is present.

} }
I have read other questions and tutorials, but I found same method of displaying, as I did in the code above. No image is displayed here. I did not find any error message in logcat. Please suggest me, any improvements in the code.
Thanks in advance.

You have a space between "/storage/ sdcard/". You should print the stacktrace to see the Exception using er.printStackTrace(). Also, you shouldn't hardcode the string path; use the Environment Class to reference file locations in a consistent way.

1) Make sure you have given permission to read external storage in your android manifest file.
2)
instead of hard coding the path to external storage use this.
File sdCardPath = Environment.getExternalStorageDirectory();
then add your folder and file name..
Bitmap bitmap = BitmapFactory.decodeFile(sdCardPath+"/DCIM/Camera/img_folder/xxx.png");
jpgView.setImageBitmap(bitmap);

Android IAB - Activity destroyed after successful purchase

I am pulling my hair out! At one point in the last week, I had this working.
I have an Android app that I am trying to add in-ap billing to. I followed the sample TrivialDrive, and my code worked a few times. Now it doesn't.
I am creating a simple trivia game that has a number of free questions, and the option to upgrade to get more questions. When the user completes the list of free questions, they are taken to a "Game Over" screen where they can erase their answers and start again, or upgrade.
When I click the "Upgrade" button, I can make a successful purchase, but as soon as the Google "Payment Successful" dialog goes away, my activity is destroyed and I am sent back to my main activity.
When I try to go back and do my purchase again, my code catches the error ("You already own this item") and handles it appropriately. My code explains to the user that they already own the upgrade, and allows them to click a button to continue playing. So it looks like the OnIabPurchaseFinishedListener is firing at this point.
I have updated the Google helper code with the latest files.
Any help or suggestions as to where to look for answers is much appreciated.
Thanks.
This is the relevant code for my activity:
public class GameOverActivity extends BaseActivity

FYI: I think I have this figured out - for anyone else that may come across it.
The activity that I was using to launch "In App Billing" was called with a "FLAG_ACTIVITY_NO_HISTORY". I did this because I didn't want the user to be able to click to go back to this "Game Over" activity.
BUT, this causes grief with "In App Billing". So, make sure you don't try to launch "In App Billing" from an activity that has had the "FLAG_ACTIVITY_NO_HISTORY" set.
My original code:
private void GameOver()
{
m_TriviaAppInstance.setGameOver(true);
Intent gameOver = new Intent(getApplicationContext(), GameOverActivity.class);
gameOver.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(gameOver);
}
Updated code:
private void GameOver()
{
m_TriviaAppInstance.setGameOver(true);
Intent gameOver = new Intent(getApplicationContext(), GameOverActivity.class);
startActivity(gameOver);
}
Peace

I'm not high enough to comment, but bless you. I had
android:noHistory="true"
set in AndroidManifest.xml for my activity and was experiencing the same problem.
Took it out and IAB is working. Yay!

Do not forget that your IabHelper.OnIabPurchaseFinishedListener is called on a different thread and before onResume() is called on your Activity!
So your UpgradeComplete() or UpgradeError() can cause a crash on older devices (Crashed every time on my Gingerbread Sony Xperia Mini Pro and worked without any trouble on Samsung Galaxy S4 (Android 4.2.2)
Caused a 3 day delay on my game..

Weird behaviour of activity lifecycle - after onResume() also onPause() called ...why?

I have a Form with edittexts and a button to call the camera with an intent (return a bitmap that is put into the imageview)...From the portrait mode i enter all edittext filed and then click the camera button which forwards me to the camera - in the camera i take a picture after what I get returned to Activity 1 (staying in portrait orientation - and all editext fields are restore in onRestoreInstanceState()) - and the last callback method of Activity 1 is onResume() (what is ok) - But the problem comes when I make an orientation change from this portrait to landscape mode - the callback methods are following
So the last callback orientation change is onPause(). I do not understand why? The problem is that onSaveInstanceState is called prior of onPause - so when I turn back to portrait mode everything will be empty (editexts, imageview..) - this strange behavior continues on every orientation change (the onPause() is called last).
I am sure this problem has to do something with the taking an image (startInentforResult....) because everything (editext fields) works fine on orientation change prior to taking an image...sometimes I can also take an image and it works fine, but in most cases not...
So my question is what is it that "drives" my Activity up to the onPause() method instead up to the onResume()?
Thanks, I would really appreciate if somebody knows the solution because I am struggling with this already a few days and could not find the solution.
The project has many classes but this is the activity code (Important to note is that the problem arises only when I take an image from camera app, after that the activity lifecycle goes crazy - also this activity is called from the main activity with 'startIntentforResult()'. I do not use 'android:configChanges="orientation|keyboardHidden"' to stop the recreatioin ):

isRecreate = false;
runOnUiThread(new Runnable() {
#Override
public void run() {
onResume();
}
});
}
}
I don't know if that's correct, but it works.
EDIT
Best solution to avoid this issues, call recreate in postDelayed with 0 delayMillis
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
recreate();
}
}, 0);

It is only normal, that strange code produces strange behavior ...
replace this line:
((MyApplicationClass) getApplication()).detach(this);
with this line:
super.onSaveInstanceState(outState);

LogCat:Default buffer size used in BufferedOutputStream constructor. It would be better to be explicit if an 8k buffer is required

I was trying to do some data loading in Splash page in my app using asynctask, but the app stuck at the splash screen, and logcat print:
Default buffer size used in BufferedOutputStream constructor. It would be better to be explicit if an 8k buffer is required.
Here are my code
package com.appkon.hdtvs;
public class Splash extends Activity {
private ChannelDB mDB;
private TextView loading;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
AppConnect.getInstance(this);
loading =(TextView)findViewById(R.id.loading);
}
private class SetDB extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
try {
if (tabIsExist(null)==true){
mDB.Reset();
Bitmap bigbang1 = BitmapFactory.decodeResource(getResources(), R.drawable.bigbang1);
Bitmap bigbang2 = BitmapFactory.decodeResource(getResources(), R.drawable.bigbang2);
mDB.createchannelEntry(new ChannelPoster(castle4, "灵书妙探 （第四季）" ,"http://appkon.com/hdtvs/channel/castle4.xml" ,"http://movie.douban.com/subject/6742616/" ));
mDB.createchannelEntry(new ChannelPoster(castle3, "灵书妙探 （第三季）" ,"http://appkon.com/hdtvs/channel/castle4.xml" ,"http://movie.douban.com/subject/4836898/" ));
}
}catch (Exception e) {
Intent i = new Intent();
i.setClassName("com.appkon.hdtvs",
"com.appkon.hdtvs.HDtvs");
finish();
startActivity(i);
}
return null;
}
protected void onProgress(String load) {
loading.setText("载入中···");
}
protected void onPostExecute(String finish) {
loading.setText("载入完成");
}
}
public boolean tabIsExist(String channelS_TABLE){
boolean result = false;
if(channelS_TABLE == null){
return false;
}
Cursor cursor= ChannelDB.check();
startManagingCursor(cursor);
try {
if(cursor.moveToNext()){
int count = cursor.getInt(0);
if(count>0){
result = true;
}
}
} catch (Exception e) {
Log.e(this.toString(),"error:"+e.toString());
Intent intent = new Intent(this,HDtvs.class);
startActivity(intent);
this.finish();
}
return result;
}
}
So what seem to be the problem? Is that because my res images are too big.

Somewhere a BufferedOutputStream is used but not constructed with a size (second argument). Maybe you used libs do the mess.
