问题 I set up some Alias for an activity with different meta-data. In this meta-data I set the name of the fragment which I then load by reflection. I don't know if that is a "clean" solution, although by using Fragments and putting the functionality inside I had one SuperActivity and 2 Empty SubActivities just to specify each one in the manifest. The question is now: Can I start an alias by an Intent? new Intent(Context, Class) won't work because I can't find a way to set up the meta-data by an

问题 I need to pass an array of Uri to another activity, to pass an array of String I use simply String[] images=getImagesPathString(); Bundle b = new Bundle(); b.putStringArray("images", images); But using an array of Uri Uri[] imagesUri=getImagesUri(); this doesn't works because there isn't a method "putUri(Uri x)" in Bundle How could I solve this problem? 回答1: You should look into the Parcelable interface to see how to pass things on an intent http://developer.android.com/intl/es/reference

问题 Did my search on the Stackoverflow and Google before already but I could not find any answer that worked out for me as I get errors when using them or that there are certain codes/parts missing or, that there could be a need to install additional library files. So basically what I want to do is to retrieve all the installed apps in the android phone and display it out but I have no clue as to how to go about doing it. I usually run into error regarding the "context" variable or that my xml

问题 In my attempts to find out how to start a new intent in my app, I've come across several ways of phrasing it. This syntax returns a runtime error, namely a ActivityNotFound exception Intent in = new Intent("com.something.something"); Of course my android manifest contains an action within the intent filter: <activity android:name=".SecondActivity" android:label="@string/title_activity_second" > <intent-filter> <action android:name="com.something.something" /> <category android:name="android

问题 My intentchooser is on the basis of a whitelist (only a selection of applictions will show up in the intent chooser). The code is on the basis of another code wich does the oposite; blacklisting applications. I got that code from here and this is the related discussion related to it.

问题 So unil this point all I can figure over was that until Android 4.2.2 there were two ways available to us : Use the logcat and extract information from it Runtime.getRuntime().exec( "logcat -v time -b main PhoneUtils:D"); I used this code to read the logcat and find out the displayMMIComplete message here Use the provided intent named com.android.ussd.IExtendedNetworkService and listen for this intent and do you task. So what I've acknoweldge until now is, Since 4.0 onwards this intent has

问题 I'm getting the following exception during an ACTION_SEND intent with a data type application/pdf : java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.SEND typ=application/pdf flg=0x3080000 cmp=com.adobe.reader/.ARSendForSignature (has extras) } This brings up a dialog to choose the desired application to receive the PDF.
