[android-developers] Is phone low memory could lead to Browser SIGSEGV in libwebcore.so?
I got many cases that browser has auto exited when user is use as normal. After check the logs, all code has SIGSEGVed inside libwebcore.so, it always hard to address the issue code as it is happened inside native C code. But on the other hand, I notice this kind of browser crash always happened in phone low memory status, and Browser also always print log as E/memlog etc. So, my question is: Is phone low memory could lead to Browser SIGSEGV in libwebcore.so?

[android-developers] How to handle phone low memory situation more efficiently?
By default, android use low memory killer to try to get out of phone low memory situation. But sometimes, the killer killed process that should not killed. That happened as the killer cannot understand what is "should not killed" from application layer. For example: 1) a persistent process hosting a service (like mp3 background playing, or a phone local search engine with DB hooks) has been killed, and the process itself will startup again. that sometimes drop into the process kill-restart-died cycle. User cannot feel that directly from UI, but that waste CPU and electric. or user will curious about why the mp3 playing in background always lost. 2) a process hosting a provider has been killed, but unfortunately a application is just calling the provider for data. user will see the application exception happened. Do you ever face a similar issue? And besides low memory killer, do you have any practice way to handle phone low memory situation more efficiently?

[android-developers] Could I read call_log by Intent?
Dear all
Here in my activity I set a call_log Uri as:
uri = Uri.parse("content://call_log/calls/4");
I wrote code as:
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(uri, getContentResolver().getType
(uri));
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
I hope I could read this call_log by auto starting activity "Dialer",
but got "stopped unexpectedly!"
BUT, uri string "content://call_log/calls" could work!
So, my question is: Is call log content provider/Resolver cannnot
support content://call_log/calls/XXX?

[android-developers] How could I run a Uri based Intent in a Tab Page?
Dear all
I added following code inside ApiDemos' Tabs3.java
--
Intent i=new Intent(Intent.ACTION_PICK,
Uri.parse("content://contacts/people"));
tabHost.addTab(tabHost.newTabSpec("tab4")
.setIndicator("contact list")
.setContent(i));
--
Could I do this? (No documents describe any restrictions)
OR, the
.setContent(new Intent(this, some_activity_inside_this_package.CLASS))
is the only intent type that TabHost supports?
BTW, the error msg I got is:
1. java.lang.SecurityException: Requesting code from
com.android.contacts (with uid 10006) to be run in process
com.example.android.apis (with uid 10052)
2. The exception path inside Android framework code:
TabHost.setCurrentTab() : 397
TabHost$IntentContentStrategy.getCotentView() : 730
LocalActivityManager.startActivity() : 335
LocalActivityManager.moveToState() : 122
ActivityThread.startActivityNow() : 1988
ActivityThread.performLaunchActivity() : 2041
ActivityThread.getPackageInfo() :1807
Could I understand as:
We cannot leverage ContentResolver's running object into our Tab page?
Thanks!

[android-developers] Re: What is the correct way to refresh UI when I use android:configChanges="keyboardHidden|orientation"
1. I don't want to recreate the activity when switching at Land &
Port, many runtime data I don't want to save and reload;
2. So I use onConfigurationChanged() facility, but I have UI for Land
& Port, What I do now is:
public void onConfigurationChanged(Configuration newConfig) {
setContentView() again as onCreate();
run findViewById()s as handlers will lost after
setContentView();
setListeners for UI widgets as they will lost also;
}
3. Is the way right I did in 2?

Hi all when I use android:configChanges="keyboardHidden|orientation" in my code, the activity will not destroy and recreate when I change from portrait to landscape, only onConfigurationChanged(newConfig) will be called by framework. The issue is: My UI cannot refresh by default, what is the correct way in onConfigurationChanged() to refresh my UI?

[android-developers] Do I using GregorianCalendar in the right way?
0. I setup my Android emulator time zone to: Australia/Adelaide GMT +10:30 1.
