Question

如果我尝试使用以下代码，则我可以使用Truecaller的SDK，并在安装了truecaller的情况下获取用户的个人资料。

//has_truecaller = TrueSDK.getInstance().isUsable(); //doesnt work before init() methof
TrueSdkScope trueScope;
TrueSdkScope.Builder sdkBuilder = new TrueSdkScope.Builder(this, sdkCallback)
            .consentMode(TrueSdkScope.CONSENT_MODE_POPUP )
            .consentTitleOption( TrueSdkScope.SDK_CONSENT_TITLE_VERIFY )
            .footerType( TrueSdkScope.FOOTER_TYPE_SKIP );

if(has_truecaller) {
        trueScope = sdkBuilder.sdkOptions( TrueSdkScope.SDK_OPTION_WITH_OTP ).build();
}else{
        //TODO get mobile number
        BaseActivity.USER_MOBILE_NUMBER = "12345677";
        trueScope = sdkBuilder.sdkOptions( TrueSdkScope.SDK_OPTION_WITH_OTP ).build();
    }
TrueSDK.init(trueScope);

但是，如果我从设备中删除Truecaller，则会出现以下错误：

Answer 1

您可以使用以下行来检查设备上是否存在Truecaller应用程序- TrueSDK.getInstance().isUsable()

在检查之前，您确实需要使用init（）方法初始化SDK。根据是否安装了Truecaller，它将返回布尔值true / false。

此外，您共享的日志是由于缺少android项目中的库依赖关系。您可以尝试在gradle中添加以下依赖项吗？这应该有助于解决错误-

compile 'com.squareup.retrofit2:retrofit:2.0.0-beta4' compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta4'

如果设备中未安装truecaller，我们可以使用Truecaller SDK吗
