Quick Start Guide

Check out our official documentation for more in depth information on installing and using Mixpanel on Android.

Installation

Dependencies in app/build.gradle

Add the following lines to the dependencies section in app/build.gradle

implementation "com.mixpanel.android:mixpanel-android:5.+"
implementation "com.google.firebase:firebase-messaging:17.3.4" // optional, if push notifications are used
implementation "com.android.installreferrer:installreferrer:1.1" // optional, if you want to know how users installed your app

Permissions in app/src/main/AndroidManifest.xml

<!-- This permission is required to allow the application to send events and properties to Mixpanel -->
<uses-permission android:name="android.permission.INTERNET" />

<!-- This permission is optional but recommended so we can be smart about when to send data  -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<!-- This permission is optional but recommended so events will contain information about bluetooth state -->
<uses-permission android:name="android.permission.BLUETOOTH" />

Integration

Initialization

Initialize Mixpanel in your main activity app/src/main/java/com/mixpanel/example/myapplication/MainActivity.java. Usually this should be done in onCreate.

String projectToken = YOUR_PROJECT_TOKEN; // e.g.: "1ef7e30d2a58d27f4b90c42e31d6d7ad" 
MixpanelAPI mixpanel = MixpanelAPI.getInstance(this, projectToken);

Remember to replace YOUR_PROJECT_TOKEN with the token provided to you on mixpanel.com.

Tracking

After installing the library into your Android app, Mixpanel will automatically collect common mobile events. You can enable/disable automatic collection through your project settings.

With the mixpanel object created in the last step a call to track is all you need to send additional events to Mixpanel.

mixpanel.track("Event name no props")

JSONObject props = new JSONObject();
props.put("Prop name", "Prop value");
props.put("Prop 2", "Value 2");
mixpanel.track("Event name", props);

Analytics Worker Fatal Exception: Strange Thread Crash

We're using 4.0.0 and seeing some very strange crashes in various places on certain devices, but not others.

The most reproducible crashing device is the incredibly slow Sony Xperia U running Android 4.0.4.

If we ever call MixpanelAPI.getInstance(context, MIXPANEL_TOKEN) then our app crashes in different places, in our network request callbacks with this:

... FATAL EXCEPTION: com.mixpanel.android.AnalyticsWorker android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. ...

An example of the rest of a stack trace is at the bottom.

This is without ever tracking any events. As soon as we stop grabbing an instance of MixpanelAPI we don't see any crashes.

UI Lag on Lollipop

While testing our app on Lollipop we noticed a huge decrease in performance on Lollipop devices. After much debugging we narrowed down the issue to MixPanel. After removing the MixPanel init everything is nice and smooth: MixpanelAPI.getInstance(this, MIXPANEL_TOKEN);

This is fairly easy to reproduce by adding a height animator on any view. The more complex the view the more janky the result, but even a view with a single color will lag enough to be noticed: ValueAnimator animator = ValueAnimator.ofInt(0, 2000); animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { @Override public void onAnimationUpdate(ValueAnimator valueAnimator) { ViewGroup.LayoutParams layoutParams = view.getLayoutParams(); layoutParams.height = (Integer) valueAnimator.getAnimatedValue(); view.setLayoutParams(layoutParams); } }); animator.setDuration(3000); animator.start();

We love MixPanel, but until we have a solution for this lag will most likely have to remove it. Please let me know how I can help you resolve it.

BLUETOOTH permission is listed as optional in docs but seems to be required

The Android setup docs under Step 2 - Add permissions to your AndroidManifest.xml: list the BLUETOOTH permission as optional but I am seeing a consistent crash for at least a Samsung SM-925T. I have not tested enough to determine if this is device specific but either way it should not happen. It causes our app to go into a crash/restart cycle of sometimes more than 10 times.

Memory leak
Hi,

After some investigation on my app, I have detected an huge memory leak coming from Mixpanel (see attached pictures). For the moment I have no idea where it comes from but it appear as soon as I call : MixpanelAPI.getInstance(my_context, MIXPANEL_TOKEN);

The android studio allocation tracker confirms that it comes from the Mixpanel package.

Following my investigation :

If I call the flush method, the leak is stopped when the app is in the bakground.

If I don't call the flush method, the leak is still present when the app is in the bakground.

If I call the getInstance(...) method with the wrong Token, I get no leaks.

I have tried with version 4.5.1 and the issue is the same (my current version is 4.6.4)

I have tried to move the Mixpanel initialization in another activity : same issue

Same issue on multiple android version (lollipop, kitkat ...).

Any idea ?

As said in the title. When we join an experiment and receive the mixpanel update callback; sometimes the tweaks variable are not up to date. Would be great to have a fix for it

Can't write track_message to server

Hi, I tried to implement library version 4.6.x on my Android app. First call to MixpanelAPI.track is working but the next calls are giving me the next error:

E/MixpanelAPI.ViewCrawler﹕ Can't write track_message to server

Hardcoded tracking to project with token 85053bf24bba75239b16a601d9387e17

The Android SDK seems to be tracking the usage (first integration on a device) of the Mixpanel SDK in a project with the token 85053bf24bba75239b16a601d9387e17, hardcoded at: ../mixpanel-android-7.0.0-sources.jar!/com/mixpanel/android/mpmetrics/MixpanelAPI.java:181

I did not find a way to deactivate that.

MPDbAdapter.generateDataString OutOfMemory Error

Hi, In low end devices i see multiple instances this MPDbAdapter.generateDataString(...) gives Out of Memory Error. I have seen the code and found we are asking for 50 records at a time.

rawDataQuery.append("ORDER BY " + KEY_CREATED_AT + " ASC LIMIT 50");

Can we make this LIMIT configurable or an optimum number which has less chances to trigger an OutOfMemory Error.

🔥 Our current Firebase BoM is 29.1.0 which corresponds to version 20.0.5 of our com.google.firebase:firebase-perf-ktx dependency.

❓ Could it be a class between our different versions of the Firebase Performance Monitoring lib?

🙇 Thanks in advance!

Source code(zip)
v7.0.0(Aug 16, 2022)
v7.0.0 (2022-08-16)

BREAKING CHANGE:

This major release removes all remaining calls to Mixpanel's /decide API endpoint. The main effect of this is that the SDK no longer fetches the remote status of your project's "Automatically collect common mobile events" setting. From this version forward, automatic event tracking can only be controlled by the, now required, parameter trackAutomaticEvents. Upon upgrading, existing implementations will need to add this parameter to their Mixpanel initializer calls.

Enhancements

Add 'trackAutomaticEvents' as a required param in getInstance' and remove Mixpanel server api call for Autotrack setting #794

v6.5.1 (2022-07-26)

Add the following new configs for you to optimize the Mixpanel tracking (#795):

     * Set maximum number of events/updates to send in a single network request
     *
     * @param flushBatchSize  int, the number of events to be flushed at a time, defaults to 50
     */
    public void setFlushBatchSize(int flushBatchSize);

    /**
     * Set an integer number of bytes, the maximum size limit to the Mixpanel database.
     *
     * @param maximumDatabaseLimit an integer number of bytes, the maximum size limit to the Mixpanel database.
     */
    public void setMaximumDatabaseLimit(int maximumDatabaseLimit);

You can also set them in AndroidManifest.xml, i.e.

        <meta-data android:name="com.mixpanel.android.MPConfig.FlushBatchSize"
            android:value="5" />

        <meta-data android:name="com.mixpanel.android.MPConfig.MaximumDatabaseLimit"
            android:value="100000000" />

v6.4.0(Jun 30, 2022)
v6.4.0 (2022-06-30)

Enhancements

Support defining multiple instances by specifying instanceName in getInstance #792

This release adds the following APIs to MixpanelAPI:

/** ... * @param instanceName The name you want to uniquely identify the Mixpanel Instance. It is useful when you want more than one Mixpanel instance under the same project token. ... **/

getInstance(Context context, String token, String instanceName) getInstance(Context context, String token, boolean optOutTrackingDefault, String instanceName) getInstance(Context context, String token, JSONObject superProperties, String instanceName) getInstance(Context context, String token, boolean optOutTrackingDefault, JSONObject superProperties, String instanceName)

Please note: If you are going to add instanceName to getInstance on your existing implementation. getInstance will start using instanceName as the instance identifier rather than token, so you might lose some of the stored properties including the distinct Id under the token. We'd recommend using it when you need to create more than one instance under the same project token. You won't lose any events and user profile updates.
