what is a dependency for android.media.tv

Question

I try to move android TV app to Android studio. When I try to compile it, I had some import errors. I couldn't find the dependency that I can add to build.gradle to fix these problem. The list of the imports are:

import android.media.tv.TvContentRatingSystemInfo;
import android.media.tv.TvContract.WatchedPrograms;
import com.android.tv.tuner.data.nano.Track.AtscCaptionTrack;
import com.android.tv.tuner.data.nano.Track.AtscAudioTrack;
import com.android.tv.tuner.data.nano.Channel;

The build.gradle is :

apply plugin: 'com.android.application'

android {
 compileSdkVersion 26
 buildToolsVersion "26.0.1"

 defaultConfig {
     applicationId "com.android.tv"
     minSdkVersion 23
     targetSdkVersion 23
     versionCode 1
     versionName "1.0"

     ndk {
         moduleName "libtunertvinput_jni"
     }
 }
 sourceSets {
     main {
         res.srcDirs = ['src/main/res', 'src/main/usbtuner-res']
         jni.srcDirs = []
     }
 }
 buildTypes {
     release {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
     }
     debug {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
     }
 }
}

dependencies {
 compile fileTree(dir: 'libs', include: ['*.jar'])
 compile files('libs/exoplayer.jar')
 compile project(':common')
 compile 'com.android.support:palette-v7:+'
 compile 'com.android.support:support-v4:+'
 compile 'com.android.support:support-annotations:+'
}

Can you post a simple project at github with that behavior? – azizbekian Sep 05 '17 at 20:46 — azizbekian, Sep 05 '17 at 20:46

android.media.tv and com.android.tv are part of Android SDK. So you don't need to include any additional libraries in gradle.build file.

Just make sure to:

Update your SDK tools to version 24.0.0 or higher

and

Update your SDK with Android 5.0 (API 21) or higher

Example,

 android {
        compileSdkVersion 26
        buildToolsVersion "26.0.1"
        defaultConfig {
            applicationId "com.example.tvapp"
            minSdkVersion 15
            targetSdkVersion 26
            versionCode 1
            versionName "1.0"
        }
}

android platform version is : API 26 androi SDK Tools : 26.0.02 but still it's not working – MRM Sep 05 '17 at 19:06
Did you try File > Invalidate Caches/Restart? Also, post your build.gradle files both app & module. @MRM – Prokash Sarkar Sep 06 '17 at 04:19

You can't import these because they have @SystemApi annotation. You can check this for the source code of TvContentRatingSystemInfo. I have also checked WatchedPrograms and it also has @SystemApi annotation. I have not checked the other three.

You need to be system app to access these. As you can see here, you need to push your app in the the \system\ folder. You can find detailed information about AOSP build system here.

Solution : Changing your android.jar to the .jar in this github should enable you to access system API. The reason is your standard android.jar doesn't have system API. So you need to get framework.jar (by adb pull) from emulator and combine it with core.jar then you can have new android.jar which contains system API (system methods and classes are available in the framework.jar from emulator).

Moreover, you should push your apk to \system\priv-app\ folder to access some system API but I don't know why I can access system API without pushing my apk to \system\priv-app\ when I use .jar from that github account.

I feel like I don't write quite clearly but at least now you have more understandings of what you're facing.

use this in your dependencies "com.android.support:support-media-compat:26.0.2"

and also use tool version "26.0.1"

compiled SDK version 26.

You can add dependencies in app level gradle.

compile 'com.google.android.libraries.tv:companionlibrary:0.1'
