[android-beginners] How do I import to eclipse projects that come with the android source?
Hello I downloaded the sourcecode of the android platform, and when I try to build the sourcecode of projects, say, packages/apps/AlarmClock I selected creating an Android project using existing code in Eclipse, but I encountered the following problem: Invalid project description. /home/eshock/android/workspace/AlarmClock overlaps the location of another project: 'AlarmClock' Any suggestions? -- Sincerely Yours, Chi Zhang elecpa...@gmail.com College of Computer Science and Technology, Zhejiang University -- You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] How to avoid jarring effect when launching an activity
Hi group, When my app icon is clicked , a black screen is displayed for a split second before my main activity comes to foreground .After goggling i found out to use Theme to avoid back screen or jarring effect .It worked out fine.Here i can display the background of my home screen for that split second mainfest.xml activity android:name=.MainActivity android:label=@string/app_name android:screenOrientation=portrait android:theme=@style/Theme.LoadingPage intent-filter action android:name=android.intent.action.MAIN / category android:name=android.intent.category.LAUNCHER / /intent-filter /activity under theme.xml resources style name=Theme.LoadingPage parent=android:Theme item name=android:windowBackground@drawable/ background_loading/item item name=android:windowNoTitletrue/item /style style name=Theme.A1LoadingPage parent=android:Theme item name=android:windowBackground@drawable/a1_loading/ item item name=android:windowNoTitletrue/item /style /resource under res/drawable/background_loading.xml bitmap xmlns:android=http://schemas.android.com/apk/res/android; android:src=@drawable/home_screen android:tileMode=repeat / But my problem is i wanted to do the same for other activity apart from main activity ,but i couldn't get the desired result.For explanation , considered i started an Activity A1 on a button click from Main Activity screen.It takes few seconds for the activity A1 to appear.I need to display the background screen of Activity A1 as soon as the button is clicked, this is just to fill the intermittent time gap before A1 actually gets displayed ,thus avoiding a standstill kind of appearance to the user . And i tried in vain .I wonder why the same that has worked on launch main activity is not working with other activities activity android:name=xx.com.A1 android:label=@string/app_name android:screenOrientation=portrait android:theme=@style/Theme.A1LoadingPage Note: I have used Threads and Handlers in activity A1 to reduce the load on onCreate. Please help me to find a correct solution. -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

[android-beginners] Re: How do I import to eclipse projects that come with the android source?
Is it caused by you have already create a project called AlarmClock under your eclipse workspace. From my experience that when import another Android project you cannot put the project into eclipse workspace. It will cause this project. You can try like this. Put your project under folder home/eshock/android/AlarmClock/ and try it again. Hope this can help you.

[android-beginners] Re: What does `adb install' do under the hood?
No stupid questions. Everyone is from fresh man. 1, adb install will install your application under folder /data/app/ with your application package name. For example, you application is MainApplication.apk and its package name is com.android.mainapplication. After install it use this command, there will be an apk under folder /data/app/ and its name is com.android.mainapplication.apk. 2, not sure about command adb shell pm install . I have never use that before. 3, adb push is to push the apk file directly into folder system/app/ and data/app/ and it is mostly like install. but with name different. For example, adb push MainApplication.apk will create a file like / data/app/MainApplication.apk. On Apr 8, 5:01 am, Chi Zhang elecpa...@gmail.com wrote: Hi everybody, this is my first post ever.

[android-beginners] Re: Registering a reciever for the BOOT_COMPLETE and android:exported attribute
Hi, Thank you for your reply. As for the reason for asking this question - I'm trying to find the most robust (future proof) way to implement the BOOT_COMPLETE receiver.

While this does work for Android 2.x, since there is no

Re: [android-beginners] Any on-phone help?
One particular app I am fond of for switching between running apps is AppSwipe! on the market... The guy who wrote the app is a beginner (me!) but still I think it does the job well. -- There are only 10 types of people in the world...

Re: [android-beginners] Android applications monitoring and profiling
The tool will monitor the number of times the application was used and the duration of time the application was used by the user. Is activity monitor used only as a part of test case or can i use activity monitor in my application. I am not getting a good example of use of Activity Monitor apart from its use in InstrumentTestcase class. I don't want to use it in an InstrumentTestCase class. I want it in my regular applications. Could anyone please share with me a nice example of actvity monitor. Any Help will be highly appreciated.

[android-beginners] Need suggestions about testing Android applications using JPF
Hello, I would be grateful if I get any suggestions about the feasibility of a project that I am trying. I am trying to test a sample android application using another tool, namely, Java Path Finder(JPF), which is a open source model checker for verifying programs and detecting errors in the program. (http:// babelfish.arc.nasa.gov/trac/jpf). What JPF does is that it explores all the interesting paths of execution of a program, and checks whether taking any of those paths would produce an error. To be able to test a program in JPF, the program must be stand-alone program having a main method. Since I cannot run an android application as a stand-alone program, I need to have another program that calls the application. I have doubts about how this can be done. I read that one can invoke an android application by calling startActivity() on the right intent, but this is possible only for applications that interact with other applications. Is there any way to call any application (even those that do not interact with other applications) from a stand-alone java program? Or in other words, is it possible to start running an application other than on an emulator? If the only way to run an android application in a tool like JPF would be, by first running emulator in JPF, this is totally different from what I am trying to achieve. Running an emulator in JPF would mean, verifying whether the emulator code is producing any errors. But what I am trying to achieve is much simpler : testing a single android application to detect any errors. I hope there is some way out here! Thank you for your inputs.

[android-beginners] disabling GMail access ... changing GMail password doesn't
I have GMail synched up with my Android. When I change my password in GMail, how come the Android continues to get access? How do I tell GMail to stop giving my Android access to my GMail account without using the Android phone ... that is, log into mail.google.com on the website and tell GMail to stop giving access to Android without changing settings on the Android phone? It would make sense to do so in case someone steals my Android phone . Thanks. Richard -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!
