Apr 17, 2010Is there anything the Dalvik VM supports (in terms of bytecode) which is not used currently because the .class files don't have it?
As an example, if people would write their own Source-to-DX converter for their functional language XYZ, would they be able to implement e. g. full tail calls although the .class file does support tail calls only under certain circumstances?
Android :: Android / Java - Call Function In Separate *.java File?
Aug 16, 2010I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

Jun 9, 2010I know the absolute path of an image (say for eg, /sdcard/cats.jpg). Is there any way to the content uri for this file? Actually in my code I download an image and save it at a particular location. In order to set the image in an ImageView currently I open the file using the path, get the bytes and create a bitmap and then set the bitmap in the ImageView. This is a very slow process, instead if I could get the content uri then I could very easily use the method ImageView.setImageUri(uri)

View 1 Replies View RelatedAndroid :: Magic Behind R Java File
Jan 12, 2010I have been having quite some problems with R.java file. Now I have decided to do a backup and delete the file to see what happens. Nothing happened, so I created an empty R.java file and hopped for the best. Now Eclipse seems to figure out that the file was tempered with and even issues a warning: R.java was modified manually! Reverting to generated version. And that's all there is. I tried building it manually but got no results. So, I have two questions: 1. what should I do to force Eclipse to generate the file. 2. what is happening here? How is the file created, where is the code that is generating the file? I would appreciate any help.
View 9 Replies View RelatedAndroid :: Installing Apk File In Java
Mar 3, 2009I'm trying to write a java program that will install an apk file on android. I saw that there is an Intent action: ACTION_PACKAGE _ INSTALL, available and the developer reference says: "Broadcast Action: Trigger the download and eventual installation of a package" So I wrote a program like so:
Intent newintent = new Intent(Intent.ACTION_PACKAGE_INSTALL); File apkFile = new File("/data/data/HelloAndroid.apk"); newintent.setData(Uri.fromFile(apkFile)); sendBroadcast(newintent);
But this fails to do the intended task (which is download and install the application). I'm not able to figure what is happening to this broadcast intent, no logs get printed in LogCat. Any pointers on where to look or how to proceed?
