This one I do not understand at all, I am trying to display a custom dialog with no title like this
d.setContentView(R.layout.incident_dialog_layout);
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
doing this gives me an error

ok that simple enough just change where the request is. So I then change it to this
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(R.layout.incident_dialog_layout);
dialog works until I start a new activity when I go back and click on the item that creates the dialog I get this error

so what does it want me to do then since I cant have it after I set the content nore can I have it before I sent the content?????
You are getting that error because the second time you set the dialog layout(this is, when you come back from the second activity), you already have content in your screen.
So, calling requestWindowFeature this second time causes the error.
You'll have to move that statement to onCreate() method, hence only one time is called requestFeature, ensuring no content is added before its call.
Based on the second comment on the question, I would guess that you are calling requestFeature() in the onStart or onResume methods.
requestFeature, as well as setContentView, should called in onCreate(). if you do it anywhere else it will get called again and cause your app to throw an error.

I have to send a byte via bluetooth, the problem is that I can not use this script because I have to write the number that is greater than 127:
mChatService.write(new byte[]{});
how can I do?
Thanks.

Receive Code
byte[] readBuf = (byte[]) msg.obj;
// construct a string from the valid bytes in the buffer
String readMessage = new String(readBuf, 0, msg.arg1);
mConversationArrayAdapter.add(readMessage);
Bytes in Java are signed so the max range is -128 to +127. If you really just need 1 byte, you can convert it to an integer on the receiving side and add 128 to it to make it in the range of 0-255.
The project was working just fine last Thursday, then, some sort of Eclipse bug caused the project properties to get all messed up.
After a splitting and frustrating headache, managed to isolate the issue and fix it....on the emulator, running it on the device gives me the original error messages:

Already tried at least 12 different ways to fix the "Couldn't load game: findLibrary returned null" error to no avail.
UPDATE: Tried using a 4.0 simulator with the exact same results, so it's definitely tied to android version; however, the project was created and is indeed built for Android 4.0 as the minimum.
Any ideas what might be happening and how to fix it?
Thanks for any replies
Most probably your library is not properly generated. Goto ProjectHome->libs->armeabi->libgame.so . libgame.so file is missing.
This file could be generated when you run create-android-project.bat or equivalent linux file.
which creates empty android project.Try copy paste this file from there.
To build cocos2dx project for Android you should perform two steps.
Build C++ libraries. It can be done with build_native.sh
Build Java Project. It can be done through Eclipse.
Such error will happen if you have missed the first step.

And My code here.
final String[] columns = { MediaStore.Images.Media.DATA,
MediaStore.Images.Media._ID };
Cursor image_cursor;
image_cursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
null, null);
int image_column_index = image_cursor
.getColumnIndex(MediaStore.Images.Media._ID);
count = image_cursor.getCount();
thumbnails = new Bitmap[count];
arrPath = new String[count];
try {
for (int i = 0; i < count; i++) {
image_cursor.moveToPosition(i);
int id = image_cursor.getInt(image_column_index);
int dataColumnIndex = image_cursor
.getColumnIndex(MediaStore.Images.Media.DATA);
thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail(
getApplicationContext().getContentResolver(), id,
MediaStore.Images.Thumbnails.MINI_KIND, null);
arrPath[i] = image_cursor.getString(dataColumnIndex);
}
} catch (Exception e) {
e.printStackTrace();
}
Sorry for my language. Thanks.
Your Part:
count = image_cursor.getCount();
thumbnails = new Bitmap[count];
May cause this. For creating Bitmaps memory-efficient you should use BitmapOptions
Try THIS instead:
Bitmap bm;
bm = Bitmap.createScaledBitmap(BitmapFactory.decodeFile(filepath),100, 100, true);
mPicture = new ImageView(context);
mPicture.setImageBitmap(bm);
See
Strange out of memory issue while loading an image to a Bitmap object
Seems like these both logs may give you the hint:
failed to allocate memory for thumbnail
content://media/external/images/thumbnails/300;
.

Does your gallery contain a lot of big pictures?
In this case you dont have a problem with your Cursor but with your memory management when it comes to bitmaps!
Furthermore you should have this permission in your manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
See also
http://developer.android.com/training/displaying-bitmaps/load-bitmap.html
Add this to your Manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
As for the the out of memory i used to get this when i have very large images in size, try to
test it in small images ..
my advice to all , try dont use large image size use https://tinypng.com/ to decrease the image size
Second increase heap size from mainfest android:largeHeap="true" in application tag to be like this
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme"
android:largeHeap="true">
and bundle max heap size
android {
compileSdkVersion 23
buildToolsVersion '23.0.0'
.......
....
dexOptions {
javaMaxHeapSize "4g"
}
}
I hope this help
Add
android:largeHeap="true"
in your Manifest application tag.

the ClassNotFoundException is usually caused when you try to run your app on lower sdk version than the target sdk
Add your HelloActivity in Manifest file.Due to this your Activity is not found and you are getting ClassNotFoundException as

Move the .mp4 file to raw/ folder. Then, replace your string with this:
String stringPath = "android.resource://[your_package_name]/raw/sample"
Please specify your location is in the sd card or in the internal storage. If it is in the sd card then it will be:
String stringPath = "/sdcard/android_asset/sample.mp4";
You have to do something like this
mediaPlayer.setDataSource(AndroidVideoPlayer.this, Uri
.parse("android.resource://com.arthisoft.tempforvideo2/R.raw.sample"));
