this is my first time integrating Google Analytics with an Android app and I'm having troubles following these indications
https://developers.google.com/analytics/devguides/collection/android/v4/
It looks like that when adding this part of the code to MainActivity.java it doesn't work so I'm not able to compile the app.
// Obtain the shared Tracker instance.
AnalyticsApplication application = (AnalyticsApplication) getApplication();
mTracker = application.getDefaultTracker();

You Just need to add your Application file to Manifest file at Application Level. Like this.
<application
android:name=".Application"
android:allowBackup="false"
android:icon="#mipmap/app_logo"
android:label="#string/app_name"
android:roundIcon="#mipmap/app_logo"
android:supportsRtl="true"
android:theme="#style/AppTheme"
tools:replace="android:allowBackup">
Also Define the Network and Network Status Primission .

I have basically created 2 Xmls. one where the user enters the phone number and then on pressing a button it goes to the OTP verification screen. But the issue here is that I am not receiving any OTP from Firebase, but after 5 sec I get a toast message that the verification failed. How could it fail if I haven't even got the message.
I also tried putting another number so that I can enter the code manually. But Firebase isn't sending me the OTP.
BASIC IMPLEMENTATION --- click Forgot Password -> Ask for Mobile Num ->Verify Otp ->Reset Password->Login Page
P.S I have enabled the phone authentication in Firebase.
OtpActivity.java
public class VerifyOtp extends AppCompatActivity {

Kindly help me out. Thankyou!!!
The verification failed because you didn't enable app verification. To do so, you can follow these steps:
Goto Google Cloud Console, Select your project and Enable Android Device Verification. Here is the direct link: https://console.cloud.google.com/apis/library/androidcheck.googleapis.com
In Android studio, go to top right corner bar, and press "Gradle". Then Expand (your project name) > app > Tasks > android, and double click on signingReport. You will find SHA1 and SHA-256 in the run window like below:
Goto your firebase console, and open tha app. Goto Project Settings. Scroll down, you'll find Add Fingerprint where you will need to insert the both SHA1 and SHA-256 key. After inserting, you will need to download the updated google-services.json. Replace the old google-services.json in the android studio project with the new one.
Now, add the browser dependency in app-level grade because the app will need to open captcha verification page from the browser:
implementation 'androidx.browser:browser:1.3.0'
Then, in Android Studio top menu Build > Clean Project and Build > Rebuild Project
Now, you're good to go.
Note: Your app may show a captcha verification web page
Add Country code (+91 for India) before the user phone number. It will Work.
NumberEnteredByUser = "91"+intent.getStringExtra("phoneNo");
I have the following problem when I run the 'app' (Android studio emulator):
Error:Execution failed for task ':app:javaPreCompileDebug'.
> Annotation processors must be explicitly declared now. The following dependencies on the compile classpath are found to contain annotation processor. Please add them to the annotationProcessor configuration.

Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior. Note that this option is deprecated and will be removed in the future.

With 8.7.0:
Annotation processors must be explicitly declared now
Do what it says
Add the second line
compile 'com.jakewharton:butterknife:8.7.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.7.0'
With 8.7.0 ... it generates more problems in my LogginActivity:
You are importing the wrong class...
Annotate fields with #BindView
That changed at Version 8.0
See the website for usage and the latest version. http://jakewharton.github.io/butterknife/
import butterknife.BindView;
..
#BindView(R.id...)
you can solve this issue by simply adding this to your app level gradle file
android{
....
defaultConfig{
....
javaCompileOptions {
annotationProcessorOptions {
includeCompileClasspath true
}
}
}
Hope its worked
Just add this line:
annotationProcessor 'com.jakewharton:butterknife-compiler:7.0.1'
in your dependencies like:
dependencies {
//...
compile 'com.jakewharton:butterknife:7.0.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:7.0.1'
}
Check this out for more details.
You can try :
// butter knife
compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
Otherwise you can try
https://github.com/avast/android-butterknife-zelezny
to auto gencode from butterknife.
I hope it can help your problem!
try this ,you need to add the annotation along with ButterKnife library..
Butterknife library
compile 'com.jakewharton:butterknife:8.8.1'
annotation for butterknife
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
Below is the fatal error that I keep getting on my App. I am trying to run a chat messenger feature on my application using Firebase. It was running however it has since kept crashing the app entirely. I've made a few edits to the code in the hope of resolving the issues, but to no avail.
I've been following this tutorial on youtbe https://www.youtube.com/watch?v=Xn0tQHpMDnM and it appears by reading the comments that no one else has a similiar error to me.
According to the log, the errors are found on line 99 - displayChatMessage(); as well as on Line 109 - adapter = new FirebaseListAdapter<ChatMessage>(this,ChatMessage.class,R.layout.chat_list_item,FirebaseDatabase.getInstance().getReference()) {
I'm hoping this maybe just a simple code error which I have created, or is it possible it could be to do with my gradle build. Below is the error log I am getting.

I had a similar problem while reading/writing to firebase database this small change worked for me. Try removing unnecessary firebase dependencies and make sure you use the same version for all the firebase dependencies for those that you use. In my case I changed my firebase dependencies from:
implementation 'com.google.firebase:firebase-firestore:11.8.0'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-core:16.0.0'
to these:
implementation 'com.google.firebase:firebase-firestore:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.google.firebase:firebase-core:11.8.0'
I'm sure you might have spent a lot of time trying to fix this. Might as well turn out worth a shot :)
I am trying to build a android application that can ranging nearby beacons, and get related information such as UUID and distance from the beacon. The problem I am facing now is that the Ranging function can not detect a single beacon at all. I am pretty sure the function is right because I have downloaded another similar demo project that can scan beacons pretty well on the same device.
The application now have no reaction at all after the beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", null, null, null)) function, and the debugger shows the thread stuck in didRangeBeaconsInRegion function and the beacons size is always 0.
Is there something wrong with my code? Or is it because my setting or configuration is not correct?

A few things to check when you cannot get detections with the Android Beacon Library:
Make sure your beacon is transmitting an AltBeacon format. If not, you simply need to register a BeaconParser expression to make it detect Eddystone or proprietary beacon types like iBeacon.
If you are unsure of the format advertised, try using the Locate app, which will tell you the format it detects.
If the device giving you trouble detecting has Android 6.0+, make sure you have obtained location permissions, as described here.

I am trying to retrieve marker location objects in order to create custom markers that will show up the Map. The project will sync but whenever I try and build an APK I get this error:
Error:Execution failed for task ':app:dexDebug'.> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files (x86)\Java\jdk1.8.0_60\bin\java.exe'' finished with non-zero exit value 1
I've tried all of the fixes from other similar questions but none have worked for me.
It happen because of heap size
I have face same issue but issue is resolved .
Please check below build.gradle/app file and do some changes in it.
Firebase version and map version should be .
Please check Code
add this two things in your gradle
multiDexEnabled true
**dexOptions {
javaMaxHeapSize "4g"

Based on this page, they solved this kind of issue by using following this steps.
Download & unzip the SDK. This should create a folder named Parse-1.xx.x (Parse-1.11.0 in my case)
Move the entire folder to /apps/libs (make sure you deleted the previous Parse-*.jar file)
Build > Rebuild project
If you have problem with bolts file you can resolve it by following this steps.
Go to: https://github.com/ParsePlatform/Parse-SDK-Android
Download the jar file
Store the downloaded jar file in the src/main/libs folder
Then add the dependency in the build.gradle(module:app) file " compile 'com.parse:parse-android:1.11.0' " -> or whatever is the version number for the jar file.
Sync the gradle file.
