Android Studio failed to convert drawable into a drawable
Try this:
- check names of drawables (file name must contain only abc...xyz 012...789 _ . in Resources folder ,
names have to start with lower case
MyImage.jpg == problem ,
names with space
my image.jpg == problem,
names with -
my-image.png == problem)
- check duplicate names with other extension ( my_image.jpg - my_image.png makes the problem)
- restart Android Studio
- if problem persist:
- check c:\Users\me\AndroidStudioProjects\myProject\myModule\build\intermediates\res\merged\debug\ drawable folder for corupted names or delete ALL drawable folders
- synk projekt, rebuild projekt
- if problem persist:
- restart Android Studio, wait for complete closure of the Android Studio!

Put your sglite database to Android Eclipse project folder named Assets.
On device will copy database file to application folder as this example:
On device will copy database file to application folder as this example:
public void createDatabase(Context myContext) throws IOException {
String sPackName = myContext.getPackageName();
InputStream assetsDB = myContext.getAssets().open("myDatabase");
OutputStream dbOut = new FileOutputStream("/data/data/"+sPackName+"/database");
byte[] buffer = new byte[1024];
int length;
while ((length = assetsDB.read(buffer))>0){
dbOut.write(buffer, 0, length);
}
dbOut.flush();
dbOut.close();
assetsDB.close();
}
You can get list by class Build
For example:
List of Build class getting from emulator:
"BOARD=unknown
BRAND=generic
CPU_ABI=armeabi
DEVICE=generic
DISPLAY=sdk-eng 2.1-update1 ECLAIR 35983 test-keys
FINGERPRINT=generic/sdk/generic/:2.1-update1/ECLAIR/35983:eng/test-keys
HOST=android-test-13.mtv.corp.google.com
ID=ECLAIR
MANUFACTURER=unknown
MODEL=sdk
PRODUCT=sdk
TAGS=test-keys
TIME=1273161972000
TYPE=eng
USER=android-build
"
For example:
if(Build.MANUFACTURER.equals("unknown")) {
// Emulator
}
List of Build class getting from emulator:
"BOARD=unknown
BRAND=generic

If you want import the backup copy to project, use: File>New>Import mudule

Add and shuffle elements in LinkedList or ArrayList Java basic example.
import java.util.Collections;
import java.util.LinkedList;
import java.util.List;
public class MainClass {
public static void main(String[] arg) {
String[] arrayOfString = {"nothing", "Hello", "people"
, "bye-bye", "hello", "world!", "End" };
List<String> arrayList = new LinkedList<String>();
for(String s: arrayOfString)
arrayList.add(s);
Collections.shuffle(arrayList);
System.out.println(arrayList);
}
}
/*
