I could see my account got created in the mobile settings->Accounts . However, when I try to get all the contacts with my account with below code ,it does not work. Its showing all apps(google.com and WhatsApp.com) contacts except my app account contacts. Cursor cursor = getContext().getContentResolver()

问题 I have an app that interfaces extensively with the contacts ContentProvider . I am looking to introduce a Wear component to my app that will make use of contact data. Is Wear able to directly access the contacts through a ContentResolver or does it have to be manually synced from the mobile device? 回答1: There is no such an API allows you to directly read contacts of your phone. You may have to consider the wearable app as a separate app from you phone side app. You should sync the contacts

问题 EDIT: I tried using this to add some words UserDictionary.Words.addWord(getActivity().getApplicationContext(),"DROIDODD",11,null,null); Now the cursor contains this word , but how do i access my other words in the personal dictionay , Where does android store the new words we enter through keyboards ?

问题 I am accessing the videos directly from content provider without storing it in my database. But it is giving me 3gp audio file along with other video and 3gp videos. how could i filter only the video files.I am working for API 8 回答1: Try this since you are working on API 8, otherwise METADATA_KEY_HAS_VIDEO could have done the job if API level >= 10. A work around using MediaPlayer. If media has height it means it is a video. public boolean isVideoFile(File file) { int height = 0; try {

问题 I'm planning the database for my app. I would like to allow others to use my data. However, I only want them to access a couple tables. Is it possible to only allow other apps to access certain tables? Having all my db code in one place (content provider) just seems like a good idea, rather than having to split it up. What would be considered best practice? 回答1: In your Android Manifest file you should for your content provider tag set an attribute grandUriPermissions to false . Thus, you

问题 I would like app to add several (2k) words to UserDictionary. I have experimented with ContentResolver().insert/bulk insert.... // array of words String[] words = getResources().getStringArray(R.array.word_array); Long start,end = null; start = System.currentTimeMillis(); int len = words.length; ContentValues[] mValueArray = new ContentValues[len]; ContentValues mNewValues = new ContentValues(); mNewValues.put(UserDictionary.Words.APP_ID, "com.my.example"); mNewValues.put(UserDictionary.Words

Since after replacing RelativeLayout with FrameLayout, I'm unable to add rule on layoutParams. protected

问题 I'm having the issue where my Android Content Provider is not being recognized in a separate build variant from an Android library. I've followed most of the ideas in: Using build types in Gradle to run same app that uses ContentProvider on one device I also followed: http://www.kevinrschultz.com/blog/2014/03/23/using-android-content-providers-with-multiple-package-names/ When I try running the app, the parent application tries to import a java class from the FYC library listed in src/main

问题 As part of a course on Android app development, I need to write my own ContentProvider. The app I'm making is a simple (? not so sure anymore) photo gallery app, with a master activity showing thumbnails in a GridView, and a detail activity showing one selected image along with some meta data. I've got something working by simply querying the MediaStore.Images.Thumbnails and Images, but -- as I said -- I need + want to learn how to "roll my own" CP. But! Every tutorial I find deals with
