Static Methods

getApplicationClassLoader() JReference
Get the initial classLoader of the application.
getCachedApplicationContext() JReference
Returns current application context on Android.
getCurrentActivity() JReference
Returns current activity.
setDylibDir({required String dylibDir}) → void
Sets the directory where dynamic libraries are looked for. On dart standalone, call this in new isolate before doing any JNI operation.
spawn({String? dylibDir, List<String> jvmOptions = const [], List<String> classPath = const [], bool ignoreUnrecognized = false, int jniVersion = JniVersions.JNI_VERSION_1_6}) → void
Spawn an instance of JVM using JNI. This method should be called at the beginning of the program with appropriate options, before other isolates are spawned.
spawnIfNotExists({String? dylibDir, List<String> jvmOptions = const [], List<String> classPath = const [], bool ignoreUnrecognized = false, int jniVersion = JniVersions.JNI_VERSION_1_6}) bool
Same as spawn but if a JVM exists, returns silently instead of throwing JvmExistsError.
