我正在尝试为一个人第一次打开应用程序做一个教程。我收到下一个错误，我不知道为什么...... :(

我在 on create 函数上调用该方法

创建时

// 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();
        }
    }

您可能有一个太大的图像，@drawable/tutorial_4导致您出现 OutOfMemoryError。

尝试使用较小的。

我猜这个问题是由于内存不足异常造成的。尝试使用低内存图像来避免这种类型的异常
