인 텐트를 사용하여 Android에서 활동을 전환하려고합니다. 그러나 내가하는 일과 상관없이 항상 충돌합니다. 나는 같은 질문에 대해 무수한 주제를 읽었으며 어느 것도 도움이되지 못했다. 그래서 저는 제 자신의 질문을 강요합니다. 나는이 프로그램을 실행하면Android 인 텐트 항상 크래시
이 응용 프로그램은 단순히 사초가 여기에
후 충돌 나의 첫 활동 (스플래쉬)인가 :
package com.redflamedeveloper.torch;

import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity {
/** Called when the activity is first created. */
MediaPlayer mpSplash;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
mpSplash = MediaPlayer.create(this, R.raw.fire); //Splash Screen sound
mpSplash.start();
Thread logoTimer = new Thread(){ //4 Second Timer
public void run() {
try {
//Waits for 4 seconds
int logoTimer = 0;
while(logoTimer <4000){
sleep(100);
logoTimer = logoTimer + 100;
}
Intent intentMain = new Intent(Splash.this, Main.class);
startActivity(intentMain);
}
catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
finally {
finish();
}
}
};
logoTimer.start(); //Starts the thread logoTimer
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mpSplash.release(); //ends sound
}
@Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();

}
