java.lang.UnsatisfiedLinkError when running with dalvikvm

I'm trying to run a JAR file I built using the following command line (from adb shell):

dalvikvm -cp /sdcard/MyJar.jar MyJar.main.Main

My Main class has only a single method main:

public static void main(String[] args)
{
    // Connect to local db
    SQLiteDatabase db = SQLiteDatabase.openDatabase(DB_PATH, null, SQLiteDatabase.OPEN_READWRITE);
}

When I run the command line it looks like the main function runs but then I get the following exception:

java.lang.UnsatisfiedLinkError: native_get_int
    at android.os.SystemProperties.native_get_int(Native Method)
    at android.os.SystemProperties.getInt(SystemProperties.java:74)
    at android.database.sqlite.SQLiteDatabase.<init开发者_运维技巧>(SQLiteDatabase.java:1846)
    at android.database.sqlite.SQLiteDatabase.openDatabase(SQLiteDatabase.java:820)
    at MyJar.main.Main.main(Main.java:146)
    at dalvik.system.NativeStart.main(Native Method)

My guess is that I need to load some kind of library to resolve this link error but I have no clue which library it is (this seems like a basic thing that probably should have been loaded by dalvikvm...).

Any ideas ?

Try running app_process instead of dalvikvm.

Vogar makes this kind of thing very easy. Check out the latest vogar from their SVN page, build it with ant, and then run this on your Linux desktop

~/Projects/vogar/bin/vogar --mode app_process ~/myapp/src/com/me/Main.java

Vogar will build your .java, create a .dex file, use adb to copy that to your device, and then execute VM on the device for you. We use it to develop Dalvik.
