我试图从另一个应用程序(应用程序B)查询自定义内容提供程序(应用程序A).

当内容提供商没有权限保护时,我可以这样做.具体来说,我在App A上构建自定义内容提供程序,并将包含URI的intent发送到App B.这是App A中的intent-sending部分.

class InsertOnClickListener implements OnClickListener{        
        public void onClick(View v) {
            ContentValues values = new ContentValues();
            values.put(DataBaseConfiguation.TableConfiguation.USER_NAME, "Jack");
            Uri uri = getContentResolver().insert(DataBaseConfiguation.TableConfiguation.CONTENT_URI, values);
            System.out.println("uri------------------->" + uri);
            // the uri above should be like "content://com.catking.contentprovider.MyContentProvider/user"
            Uri uri2 = Uri.parse("content://com.catking.contentprovider.MyContentProvider/user");
              Cursor c = managedQuery(uri2, null, null, null, null);
              String sendvalue = null;
               if (c.moveToFirst()) {
                  do{
                     System.out.println("User name:"+c.getString(c.getColumnIndex(DataBaseConfiguation.TableConfiguation.USER_NAME)).toString());               
                     sendvalue = c.getString(c.getColumnIndex(DataBaseConfiguation.TableConfiguation.USER_NAME)).toString();
                  } while (c.moveToNext());
               }
            Intent sendIntent = new Intent();
            sendIntent.setClassName("com.android.web", "com.android.web.Provid");
            sendIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            sendIntent.putExtra("name", uri2.toString());
            sendIntent.setType("text/plain");
            startActivity(sendIntent);
        }
} …
