Android Hidden API
Android Hidden API is a modified jar file which combining android.jar
from Android SDK with framework.jar
from real device. This jar makes you able to use Android internal/hidden APIs in development.
What is Android internal and hidden APIs?
Internal API is located in com.android.internal
package which available in the framework.jar
file from real Android device, while hidden API is located in android.jar
file with @hide javadoc attribute. Although the classes & methods are public
, but you cannot access it directly. There are pretty methods and resources you can use from this package. I will assume this is one API and will refer to it as to hidden API. Learn more about hidden API here.
What's the advantage?
You don't need to create new classes, constants, methods or resources which you want to use the similar function in your project. For example, if you want to create a new String
resource that contains 'accept' word. Then you want create a new translation to other language, e.g. Arabic, Indonesian, even with all languages in this world. This is too exhausting and waste your time. Why don't use com.android.internal.R.string.accept
which is retrieved via InternalAccessor.getString("accept")
?
If you plan to use only Android internal resources rather than internal classes or methods, do:
dependencies {
compile 'com.anggrayudi:android-hidden-api:0.0.5'
}
repositories {
maven { url 'https://dl.bintray.com/anggrayudi/maven/' }
// Or, you can use jCenter instead
jcenter()
}
Here's some example of accessing internal resources:
import com.anggrayudi.hiddenapi.r.Rc;
String accept = InternalAccessor.getString(Rc.string.accept);
float sbar_height = InternalAccessor.getDimension(Rc.dimen.status_bar_height);
int notif_color = InternalAccessor.getColor("config_defaultNotificationColor");
If you also want to include the internal classes or methods, do the following:
- Go to
<SDK location>/platforms/
. - Copy, paste and replace the downloaded hidden API file into this directory, e.g.
android-23/android.jar
. - Change
compileSdkVersion
andtargetSdkVersion
to 23 (for example). - Finally, rebuild your project.
Note: Higher compileSdkVersion
and targetSdkVersion
will be better.
Currently, Android Hidden API doesn't support for API 24.
