Geek: Android Development ImageView Pictures cannot be displayed

Today comes a very strange question:

ImageView cannot display the loaded local sdcard picture in Android.

The process is: first call the local camera program camera, and then load the captured pictures in the ImageView display.

2. Public class Actienvi extends Activity {
6. static final String TAG = "Actienvi";
8. private static final int req_code_camera = 0x1;
12. private String Imgpath = "";
14. private String Tempath = "";
18. @Override
20. protected void OnCreate (Bundle savedinstancestate) {
22. super.oncreate (savedinstancestate);
24. Setcontentview (R.LAYOUT.ACTI_ENVI);
28. ......
30. }
34. ......
38. @Override
40. protected void Onactivityresult (int requestcode, int resultcode, Intent data) {
42. //Photo successful and return
44. if (Requestcode = = Req_code_camera
46. && ResultCode = = ACTIVITY.RESULT_OK) {
48. This.imgpath = Tempath;
50. Bitmap BM = bitmapfactory.decodefile (this.imgpath);
52. Imgview.setimagebitmap (BM);
54. Imgview.setscaletype (Scaletype.fit_center);
56. }
58. }
62. .......
66. //Call system camera to take pictures
68. protected void Captureimage () {
70. Intent Intent = new Intent (mediastore.action_image_capture);
72. Tempath = Iohelper.generateimgpath ();
74. File out = new file (Tempath);
76. Intent.putextra (Mediastore.extra_output, Uri.fromfile (out));
78. Startactivityforresult (Intent, Req_code_camera);
80. }
84. ......
88. }

The feeling problem is more wonderful. Remember before doing a project, is also loading pictures, according to the comparison, found that the code logic, layout is no problem, the problem is where?

Search the internet for half a day, no results, feeling all caught on the edge of ... When I was about to give up, accidentally compared to the Androidmanifest.xml file, found slightly different, the difference lies in the users-sdk in the Android:targetsdkversion have and none. So I changed it.

1. <uses-sdk android:minsdkversion="8" />
2. <!--android:targetsdkversion= " --

I found the users-sdk in the Android:targetsdkversion commented out, and then debug the time, the picture actually shows. This is why AH??? Suddenly no words, ask the big God explain ah ...
