None of existing answers satisfied me, however Liberty was close. So this is how am I doing it.
First of all at the moment I am working with:
- Android Studio Beta 0.8.2
- Gradle plugin 0.12.+
- Gradle 1.12
My goal is to run Debug version along with Release version on the same device using the same ContentProvider.
In build.gradle of your app set suffix for Debug build:
buildTypes {
debug {
applicationIdSuffix ".debug"
}
}
In AndroidManifest.xml file set android:authorities property of your ContentProvider:
<provider
android:name="com.example.app.YourProvider"
android:authorities="${applicationId}.provider"
android:enabled="true"
android:exported="false" >
</provider>
In your code set AUTHORITY property that can be used wherever needed in your implementation:
public static final String AUTHORITY = BuildConfig.APPLICATION_ID + ".provider";
Tip: Before it was BuildConfig.PACKAGE_NAME
That's it! It will work like a charm. Keep reading if you use SyncAdapter!
Update for SyncAdapter (14.11.2014)
Once again I will start with my current setup:
- Android Studio Beta 0.9.2
- Gradle plugin 0.14.1
- Gradle 2.1
Basically, if you need to customise some values for different builds you can do it from the build.gradle file:
- use buildConfigField to access it from the
BuildConfig.java class
- use resValue to access it from resources e.g. @string/your_value
As an alternative for resources, you can create separate buildType or flavour directories and override XMLs or values within them. However, I am not going to use it in example below.
Example
In build.gradle file add the following:
defaultConfig {
resValue "string", "your_authorities", applicationId + '.provider'
resValue "string", "account_type", "your.syncadapter.type"
buildConfigField "String", "ACCOUNT_TYPE", '"your.syncadapter.type"'
}
buildTypes {
debug {
applicationIdSuffix ".debug"
resValue "string", "your_authorities", defaultConfig.applicationId + '.debug.provider'
resValue "string", "account_type", "your.syncadapter.type.debug"
buildConfigField "String", "ACCOUNT_TYPE", '"your.syncadapter.type.debug"'
}
}
You will see results in BuildConfig.java class
public static final String ACCOUNT_TYPE = "your.syncadapter.type.debug";
and in build/generated/res/generated/debug/values/generated.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- Automatically generated file. DO NOT MODIFY -->
<!-- Values from default config. -->
<item name="account_type" type="string">your.syncadapter.type.debug</item>
<item name="authorities" type="string">com.example.app.provider</item>
</resources>
In your authenticator.xml use resource specified in build.gradle file
<?xml version="1.0" encoding="utf-8"?>
<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
android:accountType="@string/account_type"
android:icon="@drawable/ic_launcher"
android:smallIcon="@drawable/ic_launcher"
android:label="@string/app_name"
/>
In your syncadapter.xml use the same resource again and @string/authorities too
<?xml version="1.0" encoding="utf-8"?>
<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android"
android:contentAuthority="@string/authorities"
android:accountType="@string/account_type"
android:userVisible="true"
android:supportsUploading="false"
android:allowParallelSyncs="false"
android:isAlwaysSyncable="true"
/>
Tip: autocompletion(Ctrl+Space) does not work for these generated resource so you have to type them manually
