  android exception android-asynctask sharedpreferences
  I have an application that stores some data in SharedPreferences. This control data is synchronized with a server, and when the user logins in the application I retrieve it using an AsyncTask. I’m trying to store the data retrieved in SharedPreferences again, but I’m getting a java.lang.ExceptionInInitializerError. This is the AsyncTask code:public class RetrieveLogTask extends AsyncTask<Void, Void, Boolean> {private String errorMessage;@Overrideprotected Boolean doInBackground(Void… par

  I am working on Wi-Engine and currently facing the issue while loading two sheets into zwoptex manager. In the code below I am loading two sheets (sheeta and sheetb), with two animations which are stored as actions in class (firstAction, secondAction). Later when I runAction on the sprite on button click, the firstAction runs fine but the secondAction uses the texture of firstAction with frames of second, which causes unexpected result. kindly if you can let me know what I am missing or doing wr

  android mysql sql cursor
  When I run the following query, I get unexpected results:String[] columns = new String[] { KEY_ROWID, KEY_NAME, KEY_SCORE };Cursor c = mDb.query(DATABASE_TABLE, columns, null, null, null, null, KEY_SCORE + ” DESC”, “10”);String result = “”;So, this should sort the results by the KEY_SCORE column in my table, and sort them based on descending order. When I do this, I get the following results:Mr Z – 72 Mr S – 70 Mr A – 50 Mr B – 50 Mr T – 130 Mr X – 125It therefore seems to be grouping the valu

  android fonts custom-font
  I’m using a custom font for a Japanese quiz app on Android. I tried it on a friend’s phone at a cookout, and the font did not show up (it shows up on mine and others). The font is delivered with the apk. I don’t have access to the logcat, and unfortunately forgot to check the phone model, although I think it’s kind of a budget version. Has anyone had this problem this, or have any ideas what might cause it?

  php android mysql foreach
  Trying to make manageable output for Android to convert $output into JSONObjects. When I use the commented out bottom line, it receives the data in Android’s log just fine, but can’t convert JSONArray to JSONObject – thus the desire for a foreach loop to return each SQL row on its own. I can’t see any syntax issues, so I don’t know what PHP is complaining about – any ideas? Also, when I use the commented out print code, it returns proper results, so I know it’s no problem accessing the db. Here’

  My app needs a Camera to work. However, it doesn’t matter if it’s a rear or frontal camera.Right now, I have this in my Manifest:<uses-feature android:name=”android.hardware.camera”/>To require a frontal Camera, I know I could also add this:<uses-feature android:name=”android.hardware.camera.front”/>But I’d like to support all devices that has EITHER camera. Is there anyway to do this?For example, I want to support Nexus 7 which has only a frontal camera. But I also want to support d

  android android-layout android-activity android-camera android-button
  I’m writing a program that has an activity which uses the phone’s camera to take a picture. There is a capture button under the camera’s SurfaceView. Now when the user presses the capture button, I want the surface view to show a preview of the picture, and under this preview there should be two buttons (accept and cancel). If the user presses cancel, then the program should go back to the camera preview to take another picture.I assume that I should define two layouts for this, but I don’t kno

  When implementing SurfaceHolder.Callback, some online tutorials suggest (actually, I found this is what Google wrote in API demo)public void surfaceChanged(SurfaceHolder holder, int format, int width,int height) {Parameters params = camera.getParameters();params.setPreviewSize(width, height);camera.setParameters(params);camera.startPreview();}However, this is not practical. As on real device, code like this would likely raise an exception on camera.setParameter(params), as the height and width s

  I wanted to make use of the zxing library to detect qrcodes in my app. But for the apps viewing purpose, i had to change the custom display orientation to portrait. Hence i had to integrate the whole zxing library into my app and addded camera.setDisplayOrientation(90) to the openDriver() method. After doing this, the program works, but I get “Runtime exceptions : Fail to connect to camera service” randomly.public void openDriver(SurfaceHolder holder) throws IOException {if (camera == null) {cam

  android imageview android-camera
  I understand how to use the camera intent in android to take a picture and how to save it, however, I cannot view the picture I took, within the app. The intent will take me to the camera app, I’ll snap the picture, and then app crashes. Now I’ve been trying to use the ImageView function to no avail. Can someone please tell me how to use an ImageView properly? How do I write the xml file with an imageView that has no initial source image? How do I initialize a layout that’s going to display an i
