私はこれで髪を引き裂いています!私はAndroidの初心者なので、それは非常に明白なことだと確信しています。
ScheduledThreadPoolExecutor
例外が発生していますcause: null
私が欲しいのは、アクティビティが画面に表示されるたびに実行される別のスレッドだけです!
// Instance Variables
private ScheduledExecutorService m_oScheduledExecutor = null;
@Override
protected void onResume()
{
super.onResume();
if (oScheduledExecutor == null)
{
oScheduledExecutor = Executors.newSingleThreadScheduledExecutor();
}
try
{
oScheduledExecutor.scheduleAtFixedRate({Runnable Instance HERE}, 0, 10, TimeUnit.SECONDS);
}
catch (Exception e)
{
System.out.println("(MainActivity) Error: " + e.getMessage() + " Cause: " + e.getCause());
}
}
@Override
protected void onStop()
{
super.onStop();
m_oScheduledExecutor.shutdown();
}
