I am trying to generate QRCode image using QRGen library.
I have imported qrgen-1.0.jar file to my project.
I know this question is duplicate.
I have referred following code by this link
public Bitmap qrBitmapFromString(String qrText){
ByteArrayOutputStream out = QRCode.from(qrText).to(ImageType.PNG).withSize(300, 300).stream();
byte[] data = out.toByteArray();
Bitmap bmp = BitmapFactory.decodeByteArray (data,0,data.length, null);
return bmp;
}
But I am getting the following error.

I have imported
import net.glxn.qrgen.QRCode;
import net.glxn.qrgen.image.ImageType;
2.0-SNAPSHOT should solve this https://oss.sonatype.org/content/repositories/snapshots/net/glxn/qrgen/android/2.0-SNAPSHOT/
https://github.com/kenglxn/QRGen
Finally I found and following thing working well for me.
Right click on your project
Go into Build Path
Configure Build Path
Go to Order and Export
Check your OnBarcode library
Clean your project
Think this may help some one like me.
Thanks.

I'm new in Android development, so it may be stupid question, but Google doesn't say anything about it. I use Android Studio 1.2.2 on Win 8.1
I have this error when using it on pre-lollipop devices
Is there anyway to use android.telephony.SubscriptionManager on pre-lollipop devices?

There's two android projects I want to merge, one is Main and the other is linked as Library.
But I have some troubles on this line:
Button modificarC;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_menu_calificaciones);
modificarC = (Button) findViewById(R.id.btn_aseso); //HERE
I tried Project Clean... also I have android-support-v4.jar on my dependencies

I had the same error and it turns out that the resource was overridden.
If you have one project working as a library that declares some id in a given XML file,
then your main project redefines that XML, the original id is gone, but you won't see the error until run time.
In my case, a partner deleted and committed the XML from the project, then added it back in the library project. Subclipse didn't seems to notice that because I was up to date, but the XML was there on the main project.
Well, I am Chinese. My English is not good.
I got the question too.
The solution may be:
The name of xml file is repeated, eg：a.xml is in your library project, at the same time, a.xml is in your main project.
so, please change one of the xml name.
To elaborate on #Moxor's solution, you can either:
Decalare a dummy layout xml, and assign the missing ids to some dummy Views.
Declare the missing ids as resources, the same way you declare a string resource: http://developer.android.com/guide/topics/resources/more-resources.html#Id
Cleaning the project worked for me.
I have an Activity that contains 12 ImageViews. In onCreate method I load 12 photos in these ImageViews using BitmapFactory.decodeStream(...).
When I come to this page and return back for 10 times I get the following Out of Memory Exception.
Why I get this error and how can I release resources to prevent this exception?

Maybe, decode your images with the nearest size of your ImageViews (see this : Strange out of memory issue while loading an image to a Bitmap object)
Sounds like you are switching activities the wrong way and keeping to many instances in memory. You could try setting FLAG_ACTIVITY_CLEAR_TOP on the intent that opens this activity or take a look at Activity life cycle to figure out where you should load the images.
Have you tried the following?
recycle the bitmaps like this
#Override
public void onDestroy() {
super.onDestroy();
for (int i = 0; i < 5; i++) {
TermElement e = theFiveGaugesInclRPMInPos4[i];
e.background.recycle();
e.background = null;
}
if (DEBUG)
Log.i(this.getClass().getSimpleName(), " <<-"
+ Thread.currentThread().getStackTrace()[2].getMethodName());
}
to reuse the bitmap I define it as static and just init like this:
if (faceTexture == null)
faceTexture = BitmapFactory.decodeResource(getContext()
.getResources(), faceTextureID);
check memory usage with DDMS
Now it doesn't crash anymore.
ps sorry for the formatting - it just doesn't let me format the code correctly anymore - have to reboot? :-(

I was developing a Livewallpaper which uses a open-source game engine called Andengine(andengine.org), it works fine now except sometimes when user set my Livewallpaper as wall paper, an Exception will be thrown saying "Failed to register input channel. Check logs for details.", but the werid thing is the Livewallpaper still works and did not exit.
Any idea what maybe causing this problem , or how I can fix it?
Sorry, I could only find that the InputQueue "provides a mechanism for an application to receive incoming input events. Currently only usable from native code".
Check the GLSurfaceView class in andengine. That may give you a clue of what is wrong with your wallpaper
You may also want to check why this is happening:
