[안드로이드] 카메라 이벤트 받기 동적, 정적 BroadCastReceiver 받기

카메라 이벤트 받기 동적, 정적 BroadCastReceiver 받기

1. 브로드캐스트를 정적, 동적으로 구성할때의 차이를 확인한다.

2. com.android.camera.NEW_PICTURE 및 android.hardware.action.NEW_PICTURE 을 Nuga(7.0)에서는 동적 브로드 캐스트로 만 수신 할수 있다. 그외의 Action은 동적 정적 모두 가능.

3. 안드로이드 6.0 이하 에서만 NEW_PICTURE을 정적(Manifest)으로 수신 할수 있다.

• 앱은 ACTION_NEW_PICTURE 또는 ACTION_NEW_VIDEO 브로드캐스트를 송수신할 수 없습니다. 이 최적화는 Android 7.0을 대상으로 하는 앱뿐 아니라 모든 앱에 영향을 미칩니다.
• Android 7.0부터 사용 불가 상태~

NEW_PICTURE 정적(Static) BroadCastReceiver 로 받기

 정적으로 구성시 Manifest를 이용하여, 할당한다.

▶	Mainifest.xml 등록

 리시버 등록 및 카메라 퍼미션 추가.

<!-- Add receiver --> <receiver android:name=".receiver.MyCameraBroadcastReceiver" android:enabled="true" > <intent-filter android:priority="9999999" > <action android:name="android.provider.MediaStore.ACTION_IMAGE_CAPTURE" /> <action android:name="android.intent.action.CAMERA_BUTTON" /> <action android:name="com.android.camera.NEW_PICTURE" /> <action android:name="android.hardware.action.NEW_PICTURE" /> <action android:name="android.intent.action.MEDIA_BUTTON" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="image/*" /> </intent-filter> </receiver> <!-- Camera click check--> <uses-permission android:name="android.permission.CAMERA" /> <uses-feature android:name="android.hardware.camera" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

▶	BroadCast Receiver.java

 New Picture 액션을 수신 하여, 저장 경로를 확인한다.

public class MyCameraBroadcastReceiver extends BroadcastReceiver { private String mTAG = "MyCameraBroadcastReceiver"; @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub String action = intent.getAction(); Toast.makeText(context, "New Photo is Saved as !!!! "+ action, Toast.LENGTH_LONG).show(); //abortBroadcast(); Log.d(mTAG,"New Photo Clicked"+">" + action); Cursor cursor = context.getContentResolver().query( intent.getData(), null, null, null, null); cursor.moveToFirst(); String image_path = cursor .getString(cursor.getColumnIndex("_data")); Log.d(mTAG,"New Photo is Saved as : " + image_path); Toast.makeText(context, "New Photo is Saved as : " + image_path, 1000).show(); } }

NEW_PICTURE 동적(Dynamic) BroadCastReceiver 로 받기

 동적으로 구성시 Context를 받아서 할당한다. Context 종료시 수신 받을수 없다.

▶	OnCreate() 에서 Context를 수신 받아 등록한다.

소 부연 설명

@Override public void onCreate() { super.onCreate(); Log.i("onCreate"," 시작"); MyCameraDynamicController mMyCameraDynamicController = new MyCameraDynamicController(); mMyCameraDynamicController.create(getContext()); }

▶	Dynamic BroadCastReceiver를 이용한 코드

public class MyCameraDynamicController{ //카메라를 찍었을때 인텐트 추가 하기. /*<action android:name="com.android.camera.NEW_PICTURE" /> <action android:name="android.hardware.action.NEW_PICTURE" /> <data android:mimeType="image/*" />*/ private String mTAG = "MyCameraDynamicController"; private final String ACTION_NEW_PICTURE1 = "com.android.camera.NEW_PICTURE"; private final String ACTION_NEW_PICTURE2 = "android.hardware.action.NEW_PICTURE"; private BroadcastReceiver mBroadcastReceiver = null; private Context mContext = null; public void create(Context _context){ IntentFilter pkgFilter = new IntentFilter(); pkgFilter.addAction(ACTION_NEW_PICTURE1); pkgFilter.addAction(ACTION_NEW_PICTURE2); //pkgFilter.addDataScheme("sample"); try { pkgFilter.addDataType("image/*"); } catch (MalformedMimeTypeException e) { // TODO Auto-generated catch block e.printStackTrace(); } mBroadcastReceiver = new BroadcastReceiver(){ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Log.i(mTAG,"mBroadcastReceiver"); Toast.makeText(context, "Dynamic BroadcastReceiver", Toast.LENGTH_SHORT).show(); String action = intent.getAction(); Toast.makeText(context, "Dynamic New Photo is Saved as !!!! "+ action, Toast.LENGTH_LONG).show(); //abortBroadcast(); Log.d(mTAG,"Dynamic New Photo Clicked"+">" + action); Cursor cursor = context.getContentResolver().query( intent.getData(), null, null, null, null); cursor.moveToFirst(); String image_path = cursor .getString(cursor.getColumnIndex("_data")); Log.d(mTAG,"Dynamic New Photo is Saved as : " + image_path); Toast.makeText(context, "Dynamic New Photo is Saved as : " + image_path, 1000).show(); } }; _context.registerReceiver(mBroadcastReceiver, pkgFilter); } }
