我正在尝试第一次打开应用程序时做一个教程。我收到了下一个错误，我不知道为什么...... :(
我在on create function
上调用该方法在创建
// Show tutorial if is first time.
tutorial();
方法教程
public void tutorial(){
SharedPreferences preferences = getPreferences(MODE_PRIVATE);
//boolean firstTime = preferences.getBoolean("FirstTime", false);
boolean firstTime = false; //For test purposes
if (!firstTime) {
final Dialog dialog = new Dialog(this, android.R.style.Theme_DeviceDefault_NoActionBar_Fullscreen);
// Disable title.
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
// Set dialog content layout.
dialog.setContentView(R.layout.dialog_tutorial);
SharedPreferences.Editor editor = preferences.edit();
editor.putBoolean("FirstTime", true);
editor.commit();
final View top_layout = (View)dialog.findViewById(R.id.top_layout);
final View tutorial0 = (View)dialog.findViewById(R.id.tutorial_0);
final View tutorial1 = (View)dialog.findViewById(R.id.tutorial_1);
final View tutorial2 = (View)dialog.findViewById(R.id.tutorial_2);
final View tutorial3 = (View)dialog.findViewById(R.id.tutorial_3);
final View tutorial4 = (View)dialog.findViewById(R.id.tutorial_4);
tutorial0.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
tutorial0.setVisibility(View.GONE);
tutorial1.setVisibility(View.VISIBLE);
return false;
}
});
tutorial1.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
tutorial1.setVisibility(View.GONE);
tutorial2.setVisibility(View.VISIBLE);
return false;
}
});
tutorial2.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
tutorial2.setVisibility(View.GONE);
tutorial3.setVisibility(View.VISIBLE);
return false;
}
});
tutorial3.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
tutorial3.setVisibility(View.GONE);
tutorial4.setVisibility(View.VISIBLE);
return false;
}
});
tutorial4.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
dialog.dismiss();
return false;
}
});
dialog.show();
}
}

感谢您的评论。
答案 0 :(得分：1)
您的@drawable/tutorial_4中可能有一个太大的图像，导致您出现OutOfMemoryError。
尝试使用较小的一个。

我猜这个问题是由于内存不足而导致内存图像占用不足以避免此类型异常
