13. 打开照相机

<1> Intent intent = newIntent("android.media.action.STILL_IMAGE_CAMERA");//调用照相机

startActivity(intent);

<2>Intent i = newIntent(Intent.ACTION_CAMERA_BUTTON, null);

this.sendBroadcast(i);

<3>longdateTaken = System.currentTimeMillis();

刚才找app id未果，结果发现用packagename也可以

Uri uri =Uri.parse("market://details?id=<packagename>");

这个简单多了

<2>

Uri uri = Uri.parse("content://contacts/people");

Intent it = newIntent(Intent.ACTION_PICK, uri);

startActivityForResult(it, REQUEST_TEXT);

19 打开另一程序

Intent i = newIntent();

ComponentName cn = newComponentName("com.yellowbook.android2",

"com.yellowbook.android2.AndroidSearch");

i.setComponent(cn);

i.setAction("android.intent.action.MAIN");

startActivityForResult(i, RESULT_OK);

20.调用系统编辑添加联系人（高版本SDK有效）：

it.putExtra(android.provider.Contacts.Intents.Insert.JOB_TITLE,"title");

startActivity(it);

21.调用系统编辑添加联系人（全有效）：

Intent intent = newIntent(Intent.ACTION_INSERT_OR_EDIT);

intent.setType(People.CONTENT_ITEM_TYPE);

intent.putExtra(Contacts.Intents.Insert.NAME,"My Name");

            Matrix matrix = new Matrix(); //接收图片之后放大 1.5倍
            matrix.postScale(1.5f, 1.5f);
            Bitmap bit = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(),
                    bitmap.getHeight(), matrix, true);
            imageview.setImageBitmap(bit);
