My question is specific to Android 11. Since Android 11, we now have concept of scoped storage. I have read many answers on SO but I am still confused.
Few specs of my project:
buildToolsVersion = "29.0.3"
minSdkVersion = 21
compileSdkVersion = 30
targetSdkVersion = 30
ndkVersion = "20.1.5948944"
WHAT I UNDERSTAND FROM SCOPED STORAGE IN ANDROID 11:
Earlier any app can read/write anywhere in the filesystem. Now, an app can read/write only in its private directory (excluding a few 'generally available' directories like DCIM). Is my understanding correct? (Question 1)
Private directory being : Android/data/com.myappname/files/
THERE ARE 2 SCENARIOS IN MY APP:
My app creates a file if its not created and then later reads it. I hardcoded now (for Android 11) the full path in my react native code: Android/data/com.myappname/files/myfilename. It is now working fine in android 11. Now my question is: Do I need to mention READ/WRITE_EXTERNAL_STORAGE in AndroidManifest.xml file?(Question 2) Secondly, do I need to ask user using dialog prompt in the app for any (storage) permission? (Question 3)
My app is using camera and gallery. For that I have only provided CAMERA permission in AndroidManifest.xml. Is it sufficient? What line should I add for reading from gallery? (Question 4)
Permissions from my AndroidManifest.xml is below:
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="remove" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" tools:node="remove" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" tools:node="remove" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" tools:node="remove" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" tools:node="remove" />
<uses-permission android:name="com.android.vending.CHECK_LICENSE" tools:node="remove" />
<uses-permission android:name="com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE" tools:node="remove" />
<uses-permission android:name="android.permission.USE_BIOMETRIC" tools:node="remove" />
<uses-permission android:name="android.permission.USE_FINGERPRINT" tools:node="remove" />
Malik Bilal :
\nFor app-specific storage you don't need any permission to read and write.\n\nIf you want to get some permission from the user it's good to display a dialog as a consent explaining why you need this permission.\n\nFor Gallery below android 10 you need the android.permission READ_EXTERNAL_STORAGE permission. For the Camera yes you only need to add <uses-permission android:name="android.permission.CAMERA" />. You can add this line also <uses-feature android:name="android.hardware.camera.any" /> for Play Store.\n\n",
