本文介绍了错误在呼吁从服务活动的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
下面是code我用从我的活动调用服务。
我想,当进度条达到最大值来调用服务。这将是这样做的正确方法?我的进度条达到最大值,然后我得到错误....
处理程序progressHandler =新的处理程序()
{
公共无效的handleMessage(消息MSG)
{
如果(dialog.getProgress()== dialog.getMax())
{ //Log.d(TAG的onClick:停止srvice); // stopService(新意图(oddg.this,MyService.class)); Log.d(TAG的onClick:启动服务);
startService(新意图(oddg.this,MyService.class));
} dialog.incrementProgressBy(增量);
}
};
日志:
ERROR / AndroidRuntime(725):了java.lang.RuntimeException:无法创建服务org.androidpeople.dialog.MyService:android.util.AndroidRuntimeException:
从活动上下文之外调用startActivity()需要FLAG_ACTIVITY_NEW_TASK标志。
解决方案
当你从设置标志作为你在错误日志中提到一个服务调用任何意图:
意向意图=新意图(mContext,下一步activity.class); // mContext是一个上下文变量。
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(意向);
below is the code I use to call a service from my activity. I want to call the service when the progress bar reaches its max value. what would be the right way to do it? as my progress bar reached to max then i got error....
Handler progressHandler = new Handler()
{
public void handleMessage(Message msg)
{
if (dialog.getProgress() == dialog.getMax())
{
//Log.d(TAG, "onClick: stopping srvice");
// stopService(new Intent(oddg.this, MyService.class));
Log.d(TAG, "onClick: starting service");
startService(new Intent(oddg.this, MyService.class));
}
dialog.incrementProgressBy(increment);
}
};
Logs:
ERROR/AndroidRuntime(725): java.lang.RuntimeException: Unable to create service org.androidpeople.dialog.MyService: android.util.AndroidRuntimeException:
Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag.
解决方案
When you call any intent from a service you have set flag as you have mentioned in your error log:
Intent intent = new Intent(mContext, "next activity.class"); //mContext is a Context variable.
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);
