How to create AVD with Android & (7.0) with Google APIs?

阅读更多关于 How to create AVD with Android & (7.0) with Google APIs?

When I downloaded and select "N" (API = 24) for the AVD, I see the following message on bottom right: Consider using a System Image with Google APIs to enable testing with Google Play Services. Is this image not available yet? or am I missing something? I dont see it in the SDK Manager yet. As of SDK Tools 25.1.7 and Intel x86 Atom_64 System Image Rev. 6, it appears that there is no longer a separate emulator image for the Google APIs - instead, the normal emulator image now includes the Google APIs by default. So, the message shown in the "Recommendation" section when creating an AVD appears

问题 I have an existing app that makes use of ViewPager and PagerTabStrip and this has been working for a long time with various releases of the Android SDK and the com.android.support:appcompat-v7 library.

Getting the path to SD card

阅读更多关于 Getting the path to SD card

Please read the whole post before down-voting and/or marking it as a duplicate! I'm working on an app that reads files from within a specific folder on the user's phone - either from the SD card (if there's one) or from the built in storage. Yes, the "READ_EXTERNAL_STORAGE" is mentioned in the manifest and I'm also handling the permission popup for API>23. I used to simply use File folder = new File(Environment.getExternalStorageDirectory(), "myfolder"); to get the path of the folder that is stored in the built in storage (32gb for an S7) but now I want to get the path to the SD card.

SipManager.newInstance returns null

阅读更多关于 SipManager.newInstance returns null

问题 I implement simple SIP client app for receiving calls. I go through official manual and get code from it. I noticed that SipManager.newInstance(getApplicationContext()); returns null. Documentation says that it happens when SIP API is not supported by device. However I use LG G6 with Android 7.0 and I successfully test third-party SIP clients from Google Play. So I doubt that API is not supported really. How could I check that? My manifest has all permissions ( INTERNET and USE_SIP )
