Sample for background location changes in Android "O"
License: Other
Apps running on "O" devices have significant limits placed on background
location gathering. These limits apply regardless of the targetSdkVersion
specified in build.gradle. This codelab shows how to work with these new
limits.
Old platform versions are used. An update would be great.
e.g. improved build.gradle.
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
applicationId "com.google.android.gms.location.sample.backgroundlocationupdates"
minSdkVersion 16
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.1.0'
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:26.1.0'
compile 'com.google.android.gms:play-services-location:11.8.0'
}
The Background Location Updates in Android "O" code lab has a minSdkVersion of 16 but the source code uses a number of API features that are, for example, only available in SDK 24 and 26. This results in the application halting with ClassNotFoundException when run on any device < SDK 26.
The solution is to set minSdkVersion to 26.
LocationResultHelper(Context context, List<Location> locations) {
mContext = context;
mLocations = locations;
API 26
NotificationChannel channel = new NotificationChannel(PRIMARY_CHANNEL,
API 24
context.getString(R.string.default_channel), NotificationManager.IMPORTANCE_DEFAULT);
API 26
channel.setLightColor(Color.GREEN);
API 26
channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
API 26
getNotificationManager().createNotificationChannel(channel);
}
I tried to test this Demo in ONE PLUS 3T Version and It crashed my phone (Not app only but main sytem UI app Stopped and device stared blinking). I triple check all code and everything was same so please check it with Once with One Plus 3T android O version.
Please update the lab to use getFusedLocationProviderClient
Deprecate codelab sample in favor of https://github.com/googlecodelabs/while-in-use-location
I tried to run the code in android studio, but its showing me the below error.
Also I have already installed SDK platform for Android 8.1 and 8.0
Location update not work on distance bases.
LocationRequest class setSmallestDisplacement() method not working.
Hello,
Greatly appreciate this code!, working super fine in background. But the setMaxWaitTime is so frequent and only works if i set to 10 milliseconds, anything more than that it doesn't take it.
Please have a look at it.
Thanks,
Raj
Hi Team,
First of all I would like to appreciate the team efforts been made for developing this code lab.
After reading the Android Official Documentation what I found is the codelab is using FusedLocationApi to get location updates which is now deprecated and been replaced by FusedLocationProviderClient. I have a sample ready using the new API's supporting the version from 4.x to 9.x.
Well I'll appreciate if the new API changes can be replicated in this codelab, so it'll be really good for the ones exploring out Location Api to be updated. Having said that if you suggest I can quickly fork out the branch and make the necessary changes.
Thanks

The correct name must be PRIMARY_CHANNEL
Getting LocationResult null in onReceive method of LocationUpdatesBroadcastReceiver
public class LocationUpdatesBroadcastReceiver extends BroadcastReceiver {
private static final String TAG = "LUBroadcastReceiver";
static final String ACTION_PROCESS_UPDATES =
"com.google.android.gms.location.sample.backgroundlocationupdates.action" +
".PROCESS_UPDATES";
@Override
public void onReceive(Context context, Intent intent) {
if (intent != null) {
final String action = intent.getAction();
if (ACTION_PROCESS_UPDATES.equals(action)) {
LocationResult result = LocationResult.extractResult(intent); //this result is null
