  • Why is PackageInfo.requestedPermissions always null?

    - by Luke
    I'm trying to enumerate all the permissions used by all the installed packages, however when I check the requestedPermissions property for each of my installed packages it is always null. The following is the code that does this: private HashMap<String, List<String>> buildMasterList() { HashMap<String, List<String>> result = new HashMap<String, List<String>>(); List<PackageInfo> packages = getPackageManager().getInstalledPackages(PackageManager.GET_PERMISSIONS); for (int i = 0; i < packages.size(); i++) { String[] packagePermissions = packages.get(i).requestedPermissions; Log.d("AppList", packages.get(i).packageName); if (packagePermissions != null) { for (int j = 0; j < packagePermissions.length; j++) { if (!result.containsKey(packagePermissions[j])) { result.put(packagePermissions[j], new ArrayList<String>()); } result.get(packagePermissions[j]).add(packages.get(i).packageName); } } else { Log.d("AppList", packages.get(i).packageName + ": no permissions"); } } return result; } Edit: Oops! I just needed to pass the PackageManager.GET_PERMISSIONS flag to getInstalledPackages(). Updated the code snippet.

  • Height of screen in portrait mode only?

    - by user246114
    Hi, How can I get the height of the device for portrait mode? I have to create a bitmap (which is zoomable) and I just want to get a rough idea what the tallest height should be. getResources().getDisplayMetrics().heightPixels; does the above return the height, in portrait mode only? I'm not binding my UI to this absolute value, it's just a rough fit, Thanks

  • Button style in AlertDialogs

    - by Steve H
    Does anyone know how to override the default style for AlertDialog buttons? I've looked through the Android source for themes and styles and experimented with different things but I haven't been able to find a way that works. What I've got below works for changing the backgrounds, but doesn't do anything with the buttons. myTheme is applied to the whole <application> via the manifest. (Some other items were deleted for clarity, but they only relate to the title bar.) <style name="myTheme" parent="android:Theme"> <item name="android:buttonStyle">@style/customButtonStyle</item> <item name="android:alertDialogStyle">@style/dialogAlertTheme</item> </style> <style name="dialogAlertTheme" parent="@android:style/Theme.Dialog.Alert"> <item name="android:fullDark">@drawable/dialog_loading_background</item> <item name="android:topDark">@drawable/dialog_alert_top</item> <item name="android:centerDark">@drawable/dialog_alert_center</item> <item name="android:bottomDark">@drawable/dialog_alert_bottom</item> <!-- this last line makes no difference to the buttons --> <item name="android:buttonStyle">@style/customButtonStyle</item> </style> Any ideas?

  • Validation for Alert dialog

    - by Hossam
    Hi Everyone, Im working in a game and when the player finished the level , Im asking the Player to enter his name on EditText in Alert Dialog : AlertDialog.Builder builder = new Builder(this); LayoutInflater inflater = getLayoutInflater(); // Inflate and set the layout for the dialog // Pass null as the parent view because its going in the dialog layout builder.setView(inflater.inflate(R.layout.dialog_name, null)) // Add action buttons .setPositiveButton(R.string.alertName, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { playerText = (EditText) ((AlertDialog)dialog).findViewById(R.id.username); if(playerText.getText() != null && playerText.getText().length() != 0) Helper.currentPlayer.setName(playerText.getText().toString()); //calculate the score // save in data base PlayerDataSource playerDS = new PlayerDataSource(getApplicationContext()); playerDS.open(); Helper.currentPlayer = playerDS.createPlayer(Helper.currentPlayer.getName(), Helper.currentPlayer.getScore(), Helper.currentPlayer.levels, Helper.currentPlayer.times, LanguageHelper.div); playerDS.close(); saveStmc(); mainScene.setChildScene(choicesMenu, false, true, true); } }) .setTitle("Please Enter Your name") .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { } }); alert = builder.create(); When the Player enters his name and press OK (Positive button) I will check in database if the name exists or not, if the name is exist : show Toast and not dismiss the alert to write another name. How to do that?

  • Efficiency questions

    - by rayman
    Hi, I have to manage XML documents and Strings in my app. In terms of efficiency and memory usage, will a collection like ArrayList be much more expensive than String[]? Also, I could store the content as a regular String or XML. Is working with XML also more expensive? (When I say expensive, I am referring to the use of system resources.) If there are differences, are they significant? Thanks, Ray.

  • use startActivityForResult from non-activity

    - by rayman
    Hi, I have MainActivity which is an Activity and other class(which is a simple java class), we`ll call it "SimpleClass". now i want to run from that class the command startActivityForResult. now i though that i could pass that class(SimpleClass), only MainActivity's context, problem is that, u cant run context.startActivityForResult(...); so the only way making SimpleClass to use 'startActivityForResult; is to pass the reference of MainActivity as an Activity variable to the SimpleClass something like that: inside the MainActivity class i create the instance of SimpleClass this way: SimpleClass simpleClass=new SimpleClass(MainActivity.this); now this is how SimpleClass looks like: public Class SimpleClass { Activity myMainActivity; public SimpleClass(Activity mainActivity) { super(); this.myMainActivity=mainActivity; } .... } public void someMethod(...) { myMainActivity.startActivityForResult(...); } now its working, but isnt a proper way of doing this? I`am afraid i could have some memory leaks in the future. thanks. ray.

  • ImageView doesn't rescale Image to selected size

    - by Buni
    I'm using a ImageView with a fixed size for adding an icon to a menu. In my application, I use it a lot of times, but on this ImageView the Layout Params seem to not work. Unlike the others ImageViews, in this case, I'm using a template directly, but I think that's not the problem. <?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="1dp" android:layout_height="1dp" android:scaleType="fitCenter" android:src="@drawable/ic_menu_moreoverflow_normal_holo_dark" android:contentDescription="ICON" /> Its been used in code as follows. ImageView iview =(ImageView) View.inflate(context, R.layout.icon, null); Theoretically, It should resize automatically the image, however, the images continues with the original size, although the size was 1dp. Where is the problem? Thanks a lot!

  • Resume Activity with back button

    - by Hallik
    I have an application I am creating with a DashboardActivity & a SettingsActivity. On the dashboard, I have one object displayed, but when I go into settings, I want to be able to select/deselect X options. Once the user clicks the back button, I save that data locally and to the server. Once the phone receives a success message from the server that it was stored properly, I want to reload the dashboard. I thought I would do this with the onPause and onResume, but they are called when the DashboardActivity is first created. What would be the best way to reload the dashboard by calling my web service after the settings were saved to the server? Here is what I am doing when the back button is hit @Override public boolean onKeyDown(int keyCode, KeyEvent event) { //Save data to the server once the user hits the back button if ((keyCode == KeyEvent.KEYCODE_BACK)) { SchoolSearchActivity.this.divisionProxy = new DivisionProxy(SchoolSearchActivity.this.saveUserDivisionHandler); SchoolSearchActivity.this.divisionProxy.submitUserDivisions(SchoolSearchActivity.this.userDivisions, SchoolSearchActivity.this.user_id); //SchoolSearchActivity.this.finish(); //Toast.makeText(SchoolSearchActivity.this, "Divisions Saved",Toast.LENGTH_LONG).show(); } return true; } The above opens an HTTP connection, and when the response is received, the handler processes the response. I am going to: 1) throw up a progress dialog box letting the user know it's being submitted to the server, and once a response is received, 2) go back to the previous activity and call the "refresh" webservice again. What's the best way to accomplish 1 & 2?

  • ListView OnItemClickListener Not Responding?

    - by GuyNoir
    I've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.

  • Power management on Android -- is app CPU correlated to power usage? [closed]

    - by foampile
    2 questions: Is application CPU usage on Android correlated and how highly to battery usage? In other words, are apps that suck a lot of CPU also draining the battery or not necessarily? Is there a way to itemize and display the phone's power use by application, at any given point in time as well as within defined time buckets and maybe view charts and such? Sort of like a diagnostic monitor for power usage by application or system component? Thanks

  • How to gradient fill a button's background?

    - by Samuh
    I have to create a colored button with gradient fill(starting from the middle of the button along Y axis). If I set the background property of the button to the color I want, I lose the rounded look and feel of a button and also the gradient fill(It looks like a TextView with a background). Also, I want this color to change when the user depresses the button. Can i specify this via selector XMLs(Color State Lists)? Any tutorials or links that can help me here is appreciated. Thanks.

  • Why isn't multi-touch working for my imagebuttons?

    - by Droidy
    I'm using imagebuttons that play sounds using SoundPool. Here is example code of one of the imagebuttons: ImageButton Button1 = (ImageButton)findViewById(R.id.sound); Button1.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN ) { mSoundManager.playSound(1); return false; } return false; } }); For some reason, it doesn't allow you to click multiple buttons at the same time. Is it because I'm building for 1.6 SDK? Thanks!
