Methods
-
getJavaVM(
) → Pointer< JavaVM> - Returns pointer to current JNI JavaVM instance
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.

toString(
) → String -

Static Properties
- accessors → JniAccessors
-
final
- env → GlobalJniEnv
-
Points to a process-wide shared instance of GlobalJniEnv.
final
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.
