Upgrading to Android SDK v4
We have raised the required
minSdkVersion to 21, released in 2014 and covers 95% of Android devices.
Make sure your application uses at least
21 in your
app/build.gradle, otherwise you'll see the following build error:
Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [com.wonderpush:wonderpush-android-sdk:4.0.1] [...]/.gradle/caches/transforms-2/files-2.1/110f18d74c064672b3bb9b02e46b3f51/jetified-wonderpush-android-sdk-4.0.1/AndroidManifest.xml as the library might be using APIs not available in 16 Suggestion: use a compatible library with a minSdk of at most 16, or increase this project's minSdk version to at least 21, or use tools:overrideLibrary="com.wonderpush.sdk" to force usage (may lead to runtime failures)
Add the explicit dependency on our FCM compatibility module
app/build.gradle file, replace this:
// WonderPush SDK core module implementation 'com.wonderpush:wonderpush-android-sdk:3.+'
// WonderPush SDK core module implementation 'com.wonderpush:wonderpush-android-sdk:4.+' // WonderPush compatibility module with Firebase Cloud Messaging implementation 'com.wonderpush:wonderpush-android-sdk-fcm:1.+'
Troubleshooting the "no push service available" message
If you get the following error in your logs:
E/WonderPush.Push: Cannot refresh push subscription, no push service available
You need to add the following dependency in your
// WonderPush compatibility module with Firebase Cloud Messaging implementation 'com.wonderpush:wonderpush-android-sdk-fcm:1.+'
Our SDK now depends on AndroidX to benefit from more modular dependencies.
If your application does not uses AndroidX yet, follow Android's Migrating to AndroidX guide.
Migrating is as easy as clicking on the Refactor > Migrate to AndroidX menu entry in Android Studio.
If your application does not use AndroidX you will see the following Gradle build errors:
This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry. The following AndroidX dependencies are detected: androidx.collection:collection:1.0.0, androidx.cardview:cardview:1.0.0, androidx.versionedparcelable:versionedparcelable:1.0.0, androidx.core:core:1.0.0, androidx.localbroadcastmanager:localbroadcastmanager:1.0.0, androidx.lifecycle:lifecycle-common:2.0.0, androidx.arch.core:core-common:2.0.0, androidx.constraintlayout:constraintlayout:1.1.3, androidx.constraintlayout:constraintlayout-solver:1.1.3, androidx.lifecycle:lifecycle-runtime:2.0.0, androidx.annotation:annotation:1.0.0
