I wish to delete the users entire SDcard programmatically in Android 2.2. What is the easiest way to do this? Will it require root rights? Can I just do an "rm -rf /mnt/sdcard" or do I have to make a recursive loop? Peter Knego You can delete directories with Java. You have to do it recursively if they are not empty: http://www.exampledepot.com/egs/java.io/DeleteDir.html No. All applications have full RW access to external storage. Yes you can execute shell commands (but you'll have to check if "rm" is available): Any way to run shell commands on android programmatically? Checking for

How to customize the title of a PreferenceActivity?

问题 I have the same problem like this question: Custom title bar in PreferenceActivity? After extending PreferenceActivity , I write this code in onCreate() , it just shows a blank grey title. I think it is a bug (because this solution works well with Activity). requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title); super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.main_pref); Edited : window_title.xml <

夙愿已清 提交于 2019-11-28 09:35:27
I'm developing an android application. I'm using android 2.2 In my application I am capturing GPS data and sending it to service with the 1 hour time interval. If user exits from application it's also working (it is required). I'm using 2 services (User defined), one for capturing GPS data and other for sending to the server. Here my doubt In service, can we use shared preferences. If we store any data in shared preferences in any activity of the application, will we be able to use that data in service with the help of shared preferences? You can access the default shared preferences instance,

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . It won't start the virtual device. Why can't things just work?? I'd rather not reinstall everything outside Program Files directory and I don't know and don't care what Eclipse is. 回答1: Its because of the spaces

I want minimize my app size as well as avoid the app from reverse-engineering. Can anybody help with simple answer? Proguard is part of the android eclipse plugin, so you do not have to invoke it manually. You just need to activate it on your build. To enable ProGuard so that it runs as part of an Ant or Eclipse build, set the proguard.config property in the <project_root>/project.properties file. The path can be an absolute path or a path relative to the project's root. For some situations, the default configurations in the proguard.cfg file will suffice. However, many situations are hard for

Uninstall old Android SDK versions

I installed Android SDK and it's taking almost 7 GB on my (relatively small) SSD. When I open Android SDK Manager I can see that everything is installed even older API versions. Same thing for the Extras : Can I safely un-install all the versions and only keep the latest one (API 17 in my case) ? I use Andoid SDK Tools to develop Android Apps with eclipse. Thank you. Just delete the packages you want to uninstall. You may still want to retain some of the older SDK's so as to try your apps on lower platform. I personally keep GB(API 10), ICS(API 14) and JB(API 17). Also what you can try is just

Selecting text on TextView (android 2.2)

问题 How to implement selecting text capability on Android 2.2? I searched Google but can't find a solution. 回答1: This is the only way I've found (from google) to support it for android 1.6+, it works but it's not ideal, I think in stock android you can't hold down a webview to highlight until v2.3, but I may be mistaken.. By the way this is for a webview, it might also work on textview, but I haven't tried it (Note: this is currently what my shipped app is using, so it works with all the phones I

Problems when handling orientation changes

放肆的年华 提交于 2019-11-28 04:21:38
问题 I need to handle orientation changes in my Android application. For this purpose I decided to use OrientationEventListener convenience class. But his callback method is given somewhat strange behavior. My application starts in the portrait mode and then eventually switches to the lanscape one. I have some custom code executing in the callback onOrientationChanged method that provides some additional UI handling logic - it has a few calls to findViewById . What is strange is that when

A short tutorial for people like me who had some trouble finding a way to implement TabHost and ViewPager, including page swiping with fingers and tab click to change pages.
