Native Android Troubleshooting

Troubleshooting common issues with our Native Android SDK.

📘

Troubleshooting Steps

Check the below first for common issues with Native Android Setup.

Try our example project on GitHub.

If stuck, contact support directly by sending an email to [email protected].

For faster assistance, please provide the following:

  • Your iZooto App ID (available under Settings > General > Account ID for the Android property on the panel)
  • Details, logs, and screenshots of the issue
  • Steps to reproduce

Ensure you follow all the steps mentioned below. If you are still facing issues, please reach out to Support with an error log generated using the steps given below.

Step 1: Double Check Setup Guide

Return to the setup guide you followed in Android Native SDK Setup to make sure you followed all steps while adding the iZooto SDK to your app.

Step 2: Initialise within the Application Class

Make sure you added the iZooto init within the onCreate method in your Application class.

Step 3: Check below for common issues, or send us a log if still not sure

After running through the rest of this Troubleshooting doc, share the crash logs with our support team for us to understand and assist you better.


ANR Troubleshooting

ANR errors occur web the main thread of your app is being blocked for over 5 seconds. You may see these occur along with:

Broadcast of Intent { act=com.google.android.c2dm.intent.RECEIVE flg=0x11000010 pkg=YOUR.PACKAGE.NAME cmp=your.package.name/com.iZooto.FCMBroadcastReceiver (has extras) }

This just shows how the app process started. This may appear to occur more often after adding iZooto due to push notification received events starting your app process.

The best way to dig into these ANR issues is to check the full stacktrace of all threads.

Starting at the top of each stacktrace and working down, it will help guide you on which event occurred last to trigger the ANR.

If you see iZooto in the actual stacktrace, please make sure you are testing on the latest version of our SDK. Once you verify that the issue still persists, send the full stacktrace of all threads with the ANR to [email protected] and we will help investigate.

The full log would most likely be in the low 1,000s of lines long.


Why are notifications disappearing without clicking them?

Check if you are using the Native Android method NotificationManagerCompat.from(context).cancelAll().


Failed to resolve: com.izooto:android-sdk:[1.0.0,2.1.9]

This means that Android Studio or Gradle could not download our plugin. Please check the following:
1. Open your browser to https://search.maven.org to make sure it loads on your system.
2. Make sure you are using Android Studio version 1.4.0 or newer.
3. Go to File > Settings.
4. Search for Offline work and uncheck this option.
5. Add the following to your .gradle file.

repositories {
  mavenCentral()
}

6. Try restarting Android Studio and then going to Tools > Android > Sync Project with Gradle files.


Error: Execution failed for task ':app:processDebugGoogleServices'

If you are receiving the following Android Studio error when building your project

Error:Execution failed for task ':app:processDebugGoogleServices'.
> Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 9.0.0.

Remove the following line from your .gradle file.

apply plugin: 'com.google.gms.google-services'

E/dalvikm: Could not find class

Could not find class errors are expected in the logcat for Android devices before 5.0. It is just letting you know it could not find these classes as your app loads into memory. It does not cause any issues in your app as the calls are guarded with runtime checks so they won't create any issues.


Error: java.lang.NoSuchMethodError: com.google.android.gms.common.internal.zzaa.zzb

If you see that some obfuscated Firebase or Google GMS methods are missing, it is most probably a dependency versioning conflict.

You can use the gradle dependencies and gradle dependencyInsight directives to troubleshoot which libraries are causing classes/methods to go missing. Refer to the official Gradle documentation for more information:

https://docs.gradle.org/current/userguide/tutorial_gradle_command_line.html#sec:dependency_insight

For example:

./gradlew app:dependencyInsight --configuration compile

Error:Execution failed for task ':app:processDebugManifest'

If you see the following error make sure you have completed step 2 of the Android Native Setup correctly.

Execution failed for task ':app:processDebugManifest'
Manifest merger failed with multiple errors, see logs
702702

Error:(3,0) startup failed: only buildscript {} and other plugins {} script blocks are allowed before plugins {} blocks, no other statements are allowed

Make sure you added the code from step 2 to the very top of the build.gradle file. This should be the first line of code in the file.


ERROR: AppId format is invalid

1. Make sure you have izooto_app_id in your build.gradle file and the id is correct.

android {
 defaultConfig{
    manifestPlaceholders = [
        izooto_app_id : 'YOUR_iZOOTO_ACCOUNT_ID_HERE'
        ]
    }
}

🚧

The izooto_app_id is available under Settings > General.

2. Make sure you are not replacing the application tag in your AndroidManifest.xml file with tools:node="replace"

<application
android:icon="@mipmap/ic_launcher"
tools:node="replace" <!-- Remove this line!!! -->
android:name=".ApplicationClass">

If you must replace some attributes, please use tools:replace instead of tools:node.
Example: tools:replace="icon, label"


Error: Missing Google Play Services Library

In Android Studio, open build.gradle (Module: app) and make sure you are using the latest iZooto SDK under dependencies.

dependencies {
  implementation 'com.izooto:android-sdk:[1.0.0,2.1.9]'
}
