What is the best way to detect if the paypal app is on device? about braintree_android HOT 6 CLOSED

Hi @brendanw -

When the PayPal app is not installed, braintree_android is supposed to fall back to an in-app login experience. In other words, PayPal login should be available for all users, regardless of whether or not the PayPal app is installed on their device.

Can you take a look at which case your app is hitting in this scenario? Is there a problem starting the PayPalProfileSharingActivity (an internal class of the SDK)?

Can you provide any other details that might help us reproduce the issue? (e.g. Android API version and runtime version, how common is the issue?, etc.)

If you still need to detect whether or not One Touch (authentication in the PayPal app) is available, you might be able to use PayPalTouch.available, like we do internally, but that would go outside of our typically recommended integration style.

As @mickeyreiss said braintree_android will fall back to in-app login and there should be no need to check to see if the app is installed.

@brendanw do you depend on httpcore, httpclient or httpmime? We have seen conflicts that will cause the PayPal SDK to hang at the checking device activity.

Try to replace httpcore and httpclient with httpclient-android in the dependencies.

compile ('org.apache.httpcomponents:httpclient-android:4.3.5')
compile ('org.apache.httpcomponents:httpmime:4.3.6') {
    exclude(group: 'org.apache.httpcomponents', module: 'httpclient')
}

from braintree_android.

Thanks @Ikorth that's helpful. We use the Foresee SDK which has that dependency and one other. I change our build.gradle and that resolved the spinner issue:

compile ('org.apache.httpcomponents:httpcomponents-client:4.2.2') {
    exclude(group: 'org.apache.httpcomponents', module: 'httpclient')
}
compile ('org.apache.httpcomponents:httpclient-android:4.3.5')
compile ('org.apache.httpcomponents:httpmime:4.3.6') {
    exclude(group: 'org.apache.httpcomponents', module: 'httpclient')
}

I am not sure what the root cause of the issue is. Does the Braintree SDK use the apache library? If so, I am curious why it is chosen over the standard android http client. We dislike it when 3rd party libraries use dependencies that are not absolutely 100% necessary as it increases the chances that we'll have collisions, slows down our build time w/ proguard, and bloats our code base.

More details are provided in the PayPal Android SDK Readme.

@brendanw glad to hear that fixed your problem.

If you check our build.gradle file you'll find the only dependency we have is Gson. The PayPal Android SDK is also included so merchants can use PayPal. The PayPal SDK does compile in a few dependencies that have conflicts with httpcore/httpclient. In the future this will not be an issue as we move away from using the standard PayPal Android SDK.

@braebot

I have added conflict dependency for paypal same like given in documentation (Read ME)
Like below mentioned.

compile ('org.apache.httpcomponents:httpclient-android:4.3.5')
compile ('org.apache.httpcomponents:httpmime:4.3.6') {
    exclude(group: 'org.apache.httpcomponents', module: 'httpclient')
}

But still its getting Stuck with message Checking this device in 4.1.1 devices where in 5.0 & above its working.

• targetSdkVersion 18
• compileSdkVersion 23
• buildToolsVersion '23.0.1'
• classpath 'com.android.tools.build:gradle:1.5.0'
• useLibrary 'org.apache.http.legacy'

PayPal SDK : PayPal-Android-SDK 2.13.1

compile 'com.paypal.sdk:paypal-android-sdk:2.13.1'
