在Android中启用Firebase崩溃报告

Question

  try {
    throw new NullPointerException();
} catch (NullPointerException ex) {
    FirebaseCrash.logcat(Log.ERROR, TAG, "NPE caught");
    FirebaseCrash.report(ex);
}

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

    buildscript {
        repositories {
            jcenter()
        }
        dependencies {
            classpath 'com.android.tools.build:gradle:2.1.3'
            classpath 'com.google.gms:google-services:3.0.0'

            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }

    allprojects {
        repositories {
            jcenter()
        }
    }

应用程序分级：

    apply plugin: 'com.android.application'

    android {
        compileSdkVersion 22
        buildToolsVersion '21.1.2'

        defaultConfig {
            applicationId "medimanage.corporate.mobile"
            minSdkVersion 19
            targetSdkVersion 22
            versionCode 3
            versionName "2.2"
        }

        buildTypes {
            release {
                minifyEnabled true
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }

        }

    }

    dependencies {
        compile fileTree(include: ['*.jar'], dir: 'libs')
        compile 'com.android.support:appcompat-v7:22.2.1'
        compile 'com.android.support:design:22.2.1'
