View 2 Replies View RelatedI need to implement a JNI which render image with 3-party native function. This function call is time consuming, it cost about 1s to return. I found during that time, even if I call the JNI within another Java thread, the whole Dalvik VM is blocked. UI is frozen. I guess that's because Dalvik doesn't implement Java thread with a native thread, so any time consuming native function call will block the whole VM. I wonder how to solve this problem. My best guess is I should create a pthread in JNI to call that 3-party native function. But I don't know how to implement this kind of JNI.

View 1 Replies View RelatedRecently I updated my Nexus One to Froyo (2.2) and I've noticed some significantly different behavior with SQLite. For example, I had been using a subquery (returning string data) as part of an IN clause, and the subquery portion no longer appears to function correctly. I've attached an example SQL query working with the contacts database below (Direct query shown for illustrative purposes only):
SELECT _id FROM data WHERE display_name IN (SELECT display_name FROM contacts); Up until Android 2.1 this was not a problem. After the update however, this returns an empty record set unless I run the subquery separately, surround each of the resulting values in single quotes and append those values directly into the IN clause. I have noticed this loss of functionality in multiple applications I'm working on, but I should note that it does appear to work when the results would be numeric rather than string based.
I have class A in which I have a method openfileConnec().
It was written like the below:
CODE:...............
Now I come to class B where I will call this method like the below:
CODE:.............
I was asked a question in an interview as follows:
Why does the method have a throws Exception in its declaration? Is it that on of the methods called in the implementation throws the base class exception? Also If we get a exception during calling the method (fileConnect( )) control goes to catch block. After executing catch where should the control go, what should be sent to base case?
I'm trying to override the onBackPressed() method of the ActivityGroup class:
public class MyClass extends ActivityGroup {
@Override
public void onBackPressed() {
// do something
return;
}
but I'm getting the error The method onBackPressed() of type MyClass must override a superclass method. I'm relatively new to Java, I've seen here that people do it and it works for them Why I'm getting this error? I'm writing an app for android 1.5, could the problem be here?
In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

Does the cursor uses this uri to update itself? Does it result in a call to "query" method of the contentprovider for a query. How does the cursor know what the additional where clause arguments are?

View 2 Replies View RelatedI would like to try cyanogen's latest build (although still not sure which one that is) but after trying to google everything I need answers to I am just getting more confused so I thought someone here could help.
I only have used sprecovery so this whole clockwork recovery is confusing. Says I need it but if I don't like cyanogens how hard is it to revert back to my adamz smoked glass that i have now with sprecovery? Don't even want to try and tackle the titanium backup thing.
Does Cyanogens come with busybox? Will I still have wifi tether and a kernel that supports it? What is this thing about having to install google apps in some special way as i read they are left out?
What I am looking for is all the cyanogen goodness (the ability to flip the phone and have screen rotate 180 degrees)with a smoked glass theme, stock theme or green theme, wifi tether(a must), moving wallpaper,overclocking and the ability to load my custom boot animations.
I like my Adamz smoked glass rom a lot but want to be able to rotate the phone and have the screen change. I have everything listed above except phone rotation now.
I have not had a single problem running Adamz rom or any issues with sprecovery. I can use these with ease so I am hoping someone can point me to an easy guide to make the change and answer a few of these questions.

I have an Android activity with an ImageButton. I would like to execute some logic when the button is clicked and show a different image for the pressed state, but also receive the touch event on the activity.
By default only the button receives the touch event. If I set the clickable attribute of the button to false then only the activity receives the touch event.
What's the best way to implement the touch event in the activity and the click in the button?
