问题 I'm trying to make a new PhoneAccount to use my implementation of ConnectionService. In the documentation it says I need to register a new PhoneAccount with TelecomManager and then select it in my phone-app's settings. Here's my code: TelecomManager telecomManager = (TelecomManager) getSystemService(Context.TELECOM_SERVICE); ComponentName componentName = newComponentName("se.example.connectionservicestandalonetest", "se.example.connectionservicestandalonetest.MyConnectionService");

问题 The docs claim a build.gradle like this works: android { compileSdkVersion 'android-N' buildToolsVersion 24.0.0 ... defaultConfig { minSdkVersion 'N' targetSdkVersion 'N' ... } ... } That gives me failed to find Build Tools revision 24.0.0 , when using 'com.android.tools.build:gradle:1.5.0' for the Android Plugin for Gradle and Gradle 2.5. If I look in build-tools/ in my Android SDK installation, I see 24.0.0-preview , not 24.0.0 . However, if I switch my build.gradle to use buildToolsVersion

问题 I'm trying to create a Notification on Android 7 with a custom layout but I want to use the DecoratedCustomView Style from the v7-Support Library: https://developer.android.com/reference/android/support/v7/app/NotificationCompat.DecoratedCustomViewStyle.html The reason why I want to use this style is that I want to use the notification header provided by android, as the documentation states: Instead of providing a notification that is completely custom, a developer can set this style and

问题 Is there a way to configure multi-window support for an activity only on screens large enough, e.g. tablet? https://developer.android.com/preview/features/multi-window.html#configuring doesn't mention that. Setting android:minimalHeight and android:minimalWidth seems to not help, because If the user moves the divider in split-screen mode to make an activity smaller than the specified minimum, the system crops the activity to the size the user requests. Use case: for certain activities, it

问题 Android N has a new feature - Multi Window Mode. It enables two applications to be active side-by-side (actually one one is active, other one is paused but we can see both simultaneously). I am looking for an API that I can call to have my application enter multi-window mode. I couldn't find much help in Android N SDK docs. I am trying to have two activities of my app run side by side, but without user having to do manual steps. MANUALLY ENTERING MUTLI-WINDOW MODE The user can switch into

问题 Background So far, there was an easy way to install an APK file, using this intent: final Intent intent=new Intent(Intent.ACTION_VIEW) .setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive"); But, if your app targets Android API 24 and above (Nougat - 7.0) , and you run this code on it or newer, you will get an exception, as shown here , for example: android.os.FileUriExposedException: file:///storage/emulated/0/sample.apk exposed beyond app through Intent.getData()

问题 My app uses http://prevayler.org/ for persistence, piggybacking Java Object serialization. After upgrade to Android 7.0 (Nougat) users cannot open their data, since the deserialization does not work any more: java.io.StreamCorruptedException: invalid type code: 71 at java.io.ObjectInputStream.readString(ObjectInputStream.java:1647) at java.io.ObjectInputStream.readEnum(ObjectInputStream.java:1737) ... at java.io.ObjectInputStream.readObject(ObjectInputStream.java:373) at org.prevayler

问题 I am developing an Android app for recording calls. This is my code snippet. recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT); recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC); recorder.setOutputFile(file_path); This is working perfectly for devices below android 7, but when I use Android 7 mobile devices I can hear only outgoing voice but cannot hear incoming voice . Can anyone

问题 The documentation in the N Developer Preview for their network security configuration offers these instructions: Certificate pinning is done by providing a set of certificates by hash of the public key (SubjectPublicKeyInfo of the X.509 certificate). A certificate chain is then only valid if the certificate chain contains at least one of the pinned public keys. The XML that they show is broken (missing a closing tag), but otherwise suggests that the hash is SHA256 and encoded base64: <?xml
