Method Detail

isOnUiThread

public static boolean isOnUiThread()

Returns:

true if the current thread is the UI thread.

runOnUiThread

public static void runOnUiThread(java.lang.Runnable runnable)

Runs the given Runnable on the UI thread.

postOnUiThread

public static void postOnUiThread(java.lang.Runnable runnable,
                                  long delayMills)

Posts the given Runnable on the UI thread.

checkIsOnMainThread

public static void checkIsOnMainThread()

Throws exception if called from other than main thread.

executeUninterruptibly

public static void executeUninterruptibly(ThreadUtils.BlockingOperation operation)

Utility method to make sure a blocking operation is executed to completion without getting interrupted. This should be used in cases where the operation is waiting for some critical work, e.g. cleanup, that must complete before returning. If the thread is interrupted during the blocking operation, this function will re-run the operation until completion, and only then re-interrupt the thread.

joinUninterruptibly

public static boolean joinUninterruptibly(java.lang.Thread thread,
                                          long timeoutMs)

joinUninterruptibly

public static void joinUninterruptibly(java.lang.Thread thread)

awaitUninterruptibly

public static void awaitUninterruptibly(java.util.concurrent.CountDownLatch latch)

awaitUninterruptibly

public static boolean awaitUninterruptibly(java.util.concurrent.CountDownLatch barrier,
                                           long timeoutMs)

waitUninterruptibly

public static void waitUninterruptibly(java.lang.Object object)

invokeAtFrontUninterruptibly

public static <V> V invokeAtFrontUninterruptibly(android.os.Handler handler,
                                                 java.util.concurrent.Callable<V> callable)

Post |callable| to |handler| and wait for the result.

invokeAtFrontUninterruptibly

public static void invokeAtFrontUninterruptibly(android.os.Handler handler,
                                                java.lang.Runnable runner)

Post |runner| to |handler|, at the front, and wait for completion.

concatStackTraces

public static java.lang.StackTraceElement[] concatStackTraces(java.lang.StackTraceElement[] inner,
                                                              java.lang.StackTraceElement[] outer)
