Macros§

AttachGuard: A RAII implementation of scoped guard which detaches the current thread when dropped. The attached JNIEnv can be accessed through this guard via its Deref implementation.
GlobalRef: A global JVM reference. These are “pinned” by the garbage collector and are guaranteed to not get collected until released. Thus, this is allowed to outlive the JNIEnv that it came from and can be used in other threads.
JClass: Lifetime’d representation of a jclass. Just a JObject wrapped in a new class.
JNIEnv: FFI-compatible JNIEnv struct. You can safely use this as the JNIEnv argument to exported methods that will be called by java. This is where most of the magic happens. All methods on this object are wrappers around JNI functions, so the documentation on their behavior is still pretty applicable.
JObject: Wrapper around [sys::jobject] that adds a lifetime to ensure that the underlying JNI pointer won’t be accessible to safe Rust code if the object reference is released.
JObjectArray: Lifetime’d representation of a jobjectArray which wraps a JObject reference
JString: Lifetime’d representation of a jstring. Just a JObject wrapped in a new class.
JavaVM: The Java VM, providing Invocation API support.
NativeMethod: Native method descriptor.

DroidWrapError: 错误类型
JValueGen: Rusty version of the JNI C jvalue enum. Used in Java method call arguments and returns.
JniError
ReleaseMode: ReleaseMode

JBooleanArray: Lifetime’d representation of a crate::sys::jbooleanArray which wraps a JObject reference
JByteArray: Lifetime’d representation of a crate::sys::jbyteArray which wraps a JObject reference
