startActivity打开图库应用程序但不是可绘制的jpg图像（Android 4.0）？

Question

我有一个非常简单的Android应用程序，用于在drawable中打开图库。 但是当我使用调试模式在Galaxy Nexus（4.0.2）上运行它时，它会打开图库而不是图像。 我确定我正确地写了文件名，我在drawable，drawable-hdpi，drawable-ldpi，drawable-mdpi甚至drawable-xhdpi中都有相同的副本：

package kailu.apps.map;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;

public class SingaporeMapActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Intent myIntent = new Intent(Intent.ACTION_VIEW);
        myIntent.setData(Uri.parse("android.resource://kailu.apps.map/" + R.drawable.singapore_mrt2012));
        myIntent.setType("image/jpeg");
        startActivity(myIntent);
    }
}

在日志中，您无法看到意图。

这是logCat：

使用Android模拟器我得到“不幸，相机已经停止”

谢谢你的帮助。

Answer 1

您的资源的Uri格式不正确。 由于它在您的包中没有解析为任何内容，因此库将按预期打开。
