my app has widgets that have an ImageView and a TextView. On the onUpdate() method of the WidgetProvider, I put a Bitmap inside the ImageView this way:
CODE:..................
setColor() method is this:
CODE:..........
The problem is that sometimes the widget throws a RuntimeException because somebody has recycled the Bitmap, and I don't know what to do.

I am getting the following logs when i am changing the wallpaper for Homescreen. Even i am recycling the bitmap is done when the wallpaper changes in OnWallpaperChanged(). Still i m getting the bellow error.

I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.
I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?
My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

I'm trying to add ScoreNinja, the global high score system, to my Android game, and it works fine when I load it on my phone, but when I release it into the wild, I got crash reports saying: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
Here is part of the call stack:
android.os.Handler.<init>(Handler.java:121)
android.app.Dialog.<init>(Dialog.java:99)
android.app.AlertDialog.<init>(AlertDialog.java:65)
android.app.AlertDialog.<init>(AlertDialog.java:61)....
I thought the main thread had prepare() called automatically, and if not, why would it work fine for me but not anyone else?

I've an application that you can show and close several Dialogs with:

I would like to do some tests on SlidingDrawer however i always found RuntimeException when SlidingDrawer.onMeasure is called i check the code and think the exception is caused by unspecified MeasureSpec
so i would like to ask how to setup the MeasureSpec in SlidingDrawer?
This code works fine if I move the findViewById call in to the Activity. Any hints as to why it doesn't work from inside the LearningView class? I've tried moving the TextView inside the com.example.LearningView tag but no joy. I'd prefer to get the TextView from within the SurfaceView subclass as I feel it's more logical to treat the TV as a "child" of the SV.
This is a contrived example I wrote to figure out the problem in a larger application, but the gist of it is the same, and the stack trace is basically the same.
For what it is worth, the findViewById call is returning null, which obviously threw NullPointerExceptions in some attempts to fix this.
As you can probably gather from my attempts I'm flying blind on this one.

I get the following error in logcat: java.lang.RuntimeException: Binary XML file line #26: You must supply a layout_height attribute. Can you please tell me which xml file that I am missing? And it said 'binary xml', does it mean it is actually line 26 in my file? or it is line 26 in the file after it compiles to be a binary xml file?..........
View 4 Replies View RelatedI wrote an android app and so far it works perfect except for on one phone. It is the exact phone that I have with 2.2 on both phones and mine works perfect. The other phone is getting force close all the time but only when opening an activity that queries my image DB and tries to show a gallery. Every activity crashes in the same place, the viewimages. At first I thought it was the intent that was doing it but one of the activitys does not have the intent, it opens the images below the gallery. This works on the emulator, on my moto droid and on a few other different droids. Here is the code for the gallery and my bitmap decoder.
The error is below that.

I want to draw a shape(many circles particularly) into a Specific Bitmap. I have never used canvas / 2D graphs etc. As i see it i create a Drawable put the bitmap in it then "canvas-it" to the shapes i want etc.
View 1 Replies View RelatedI'm calling Debug.startMethodTracing("fnord") and I'm getting a java.lang.RuntimeException: file open failed message. It looks like I'm supposed to have the android.permission.WRITE_EXTERNAL_STORAGE permission set. But how do you set that permission when you're debugging through Eclipse? Aren't permissions normally set at install time (which doesn't happen in a normal way when you're debugging)?

I'm trying to use a custom class (be.myname.rssreader.util.Global) extending android.app.Application, but when I try to use its accessors, I get the following exception:
CODE:...........
Before you ask, yes, it's in my manifest, as follows:
<application android:name=".util.Global" android:icon="@drawable/icon"android:label="@string/app_name" android:debuggable="true">
The code where the exception is thrown is this:
global.setService(new FeedService(getApplicationContext()));
It's placed in the onCreate of my main Activity, immdiately after the calls to super.onCreate and setContentView.
I found this example where they used PowerMock and EasyMock to stub/mock the Menu and MenuItem classes for android. I have been trying to do something similar with PowerMock and Mockito with the Activity class.
I understand that a lot of the methods are final and that in the Android.jar they all just throw RuntimeException("Stub!").
I also understand that this test isn't complete but I just wanting to see if it is possible to mock the android Activity class.
But given that PowerMock allows you to mock classes with final methods shouldn't this code work?
CODE:............
I would think that the RuntimeException would no longer occur and "Title" would be returned but it still throws the exception.
I have tried all sorts of different things like doReturn("Title").when(mockActivity).getTitle(); and suppress(constructor(Activity.class));
I'm trying to figure out how to draw on a bitmap in android, and keep a copy of these changed bitmaps for an undo function.
Bitmap b = ...
Paint p = new Paint();
canvas.drawBitmap(b, new Matrix(), null);
canvas.drawCircle(0,0,20,20);
//does Bitmap b have the circle drawn on it next time?
Or how do I get the bitmap after its been drawn on with the canvas(I want to preserve a stack of bitmaps with the changes applied by canvas drawing)? Maybe I'm going about this entirely wrong.
I am trying to grayscale bitmap as follows, But it is crashing as soon as I run this method.
The problem is in last line. How can I assign "int" to "Color"? Or are there any better ways?
CODE:................
I want to get the bitmap that is drawn when a textview is displayed but without displaying the textview in the activity. something like this:
TextView t = new TextView(this);
t.forceToDrawItself();
Bitmap b=t.getViewBitmap();
how is this possible?
Does anybody knows how can I put a Bitmap on top of a button, but without taking the whole surface?

View 7 Replies View RelatedI have a Bitmap image and i want to forward the bitmap to another activity. I have two activities Activity A and Activity B. This is how I started the Activity B
startActivityForResult(new Intent(Activity A.this, Activity B.class), 120);
in activity B
private void forwardImage(Bitmap bit) {
Intent i = new Intent(MMS.this, Compose.class);
i.putExtra("MMS", bit);
setResult(RESULT_OK, i);
finish(); }
This is not forwarding to Activity A but if I put a String to the intent it'll forward. This is how I listen to result in Activity A
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
// super.onActivityResult(requestCode, resultCode, data);
switch (resultCode)
case RESULT_OK: Intent intent = getIntent();
Bitmap bitmap = (Bitmap) intent.getParcelableExtra("MMS");
mmsImage.setImageBitmap(bitmap);
default: break;
} }
How can I pass a bitmap.
I have a bitmap displayed on ImageView now i want to give a facility to write comment typed by the user on that bitmap.i tried using Canvas canvas = new Canvas(srcBitmap); canvas.drawText("Hello", 100,100,null);but this is giving me following error java.lang.IllegalStateException: Immutable bitmap passed to Canvas constructor later on i want to save this whole image a bitmap.
