问题 I used this answer to create a standalone Android library project that has the ZXing source code in it (ZXing v2.1). It compiles fine and if I run CaptureActivity, I can read a QR code as expected. I have another Android project from which I want to pull in this library. I have set that library relationship up correctly. The issue I am having is, how do I launch my local copy of the ZXing scanner via IntentIntegrator (mentioned here). I tried modifying the IntentIntegrator.initiateScan()

问题 I am unable to successfully use the Google System Voice Actions "Search in App" ( com.google.android.gms.actions.SEARCH_ACTION ) on an app that I have already published onto Google Play (Private Channel) and downloaded onto my phone. The intent with the query extra from the search action is to be passed on to MainActivity after matching the intent filter. Before publishing the app, I have already tested the app using the adb command below which works perfectly: adb shell am start -a "com

问题 My app adds contact ' Bob ' to the address book using a custom ContentProvider . In the Android Contacts app, Bob shows up just as any other (Google) contact. But when I edit Bob in the Contacts app, the data provided by my application is not editable. So far so good. My question is : From within my app, is there a way to fire up the Contacts app, in a way that allows the user to edit the portion of Bob that belongs to my app? I have tried to use the corresponding Intent , as described in

问题 I am using Android's default share intent to share an image to other apps. But I would like to add an option like Save to Gallery which saves that Image directly to Gallery in media or images or my app's folder. Currently I am using the simple code to share image: Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); shareIntent.setType("image/jpeg"); startActivity(Intent.createChooser(shareIntent, "Share

问题 I am getting different numbers from Contacts and passing them to SMS application. I am using the following: Intent intent = new Intent( Intent.ACTION_VIEW, Uri.parse( "sms:"+numbers) ); //numbers separated with ; intent.putExtra( "sms_body", body ); startActivity( intent ); The problem is if I separate numbers with ' ; ', it does not work on Galaxy S but works on others like HTC, Samsung Gio etc...

问题 I'm brushing on my Android dev skills and have been playing around with the Architecture Components. So I created an entity class using Room annotations for persistence to the database and implemented Parcelable on the entity class partly for the purpose of putting the entity object into an Intent object and passing it between activities/fragments. I just want to know if this is a good practice. Are there any cons of using such approaches such as database leaks or security flaws? Just curious
