Security exception on reading attachment from gmail app in my app android
android
Solution
The intent filter requires both content and file scheme types, with the mimetype application/octetstream
<intent-filter>
<action android:name="android.intent.action.VIEW"/>
<category android:name="android.intent.category.BROWSABLE"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:scheme="file" android:pathPattern=".*\\.inform" android:mimeType="application/octet-stream"/>
<data android:scheme="content" android:pathPattern=".*\\.inform" android:mimeType="application/octet-stream"/>
as per the Android documentation, "If a scheme is not specified for the intent filter, all the other URI attributes are ignored." With the scheme and URI attributes removed, the only other way to filter the intents is using Mime type, and we all know that custom file extensions do not have registered mime types.
For reference, URI are of the form:
scheme://host:port/path
pathPrefix
pathPattern
So without a scheme, all of that drops. After discovering the above, I tried the obvious -- use a " * " for the scheme, and even tried " .* ". Neither of those worked. I hope someone else can build off my trials. But I believe it has to do with selecting the correct scheme. Unfortunately, the only schemes I know of are http https content and file, and none of the above are the magic bullet.
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="application/*" host="*" android:pathPattern=".*.ext" android:scheme="content" />
</intent-filter>
This intent will cause gmail to display the Download / Preview buttons. In fact, this will also cause your app to open when .ext files are sent as attachments to the regular email client as well.

Problem
In our application we need to read attachments from email clients and upload it to server. For default android email client everything works fine,but for gmail application facing ``` java.lang.SecurityException: Permission Denial: opening provider com.google.android.gm.provider.MailProvider from ProcessRecord (pid=11298, uid=10068) requires com.google.android.gm.permission.READ_GMAIL or com.google.android.gm.permission.WRITE_GMAIL ``` Have even tried giving Gmail read write permissions but did not work. Observations are It is working fine for Nexus but for samsung devices 4.2 and 4.1,working fine initially if activity is created for first time,but if activity is in background throwing above said exceptions. Trying to get attachment file name using below code. ``` Cursor cursor = getContentResolver().query(openIntent.getData(), new String[] { MediaStore.MediaColumns.DISPLAY_NAME }, null, null, null); cursor.moveToFirst(); int nameIndex = cursor .getColumnIndex(MediaStore.MediaColumns.DISPLAY_NAME); if (nameIndex >= 0) { NCUtil.clickedImageTitle = cursor.getString(nameIndex); path = cursor.getString(nameIndex); } cursor.close(); ``` My Manifest file ``` <activity android:name="com.ncomputing.vspacemobile.NCMainActivity" android:configChanges="orientation|keyboard|keyboardHidden|screenSize" android:excludeFromRecents="true" android:launchMode="singleTask" android:screenOrientation="sensorPortait" android:theme="@android:style/Theme.NoTitleBar" android:windowSoftInputMode="adjustPan" > <!-- For email attachments --> <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <data android:mimeType="application/pdf" /> <data android:mimeType="application/msword" /> <data android:mimeType="application/vnd.openxmlformats-officedocument.wordprocessingml.document" /> <data android:mimeType="application/vnd.ms-excel" /> <data android:mimeType="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" /> <data android:mimeType="application/vnd.ms-powerpoint" /> <data android:mimeType="application/vnd.openxmlformats-officedocument.presentationml.presentation" /> <data android:mimeType="text/plain" /> <data android:mimeType="text/comma-separated-values" /> <data android:mimeType="application/rtf" /> </intent-filter> </activity> ``` User permissions ``` <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> ``` Please let us know how can i make it work,i need the activity launch mode as singleTask and access the attachments.
