Question

我正在构建一个Android应用程序，当我中途使用SDK管理器更新我的SDK版本时，我还将Android Studio更新为1.3.2。执行此操作后，我的应用程序在某些设备上崩溃，但不是全部。

我得到的错误是

Process: com.pickingo.fe, PID: 11543

            at java.lang.Class.classForName(Native Method)

            at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:696)

这是我的Application.java类

import android.content.Context;

import com.activeandroid.ActiveAndroid;
import com.pickingo.fe.notification.NotificationManager;
import com.pickingo.fe.preference.PreferenceManager;
import com.pickingo.fe.sync.ServerUpdatePusher;
import com.pickingo.fe.test.StoreLogcat;

public class Application extends android.app.Application {


    public static boolean init = true;

    public static final String PF_INIT = "pf_init";


    @Override
    public void onCreate() {
        super.onCreate();
        new Thread(new StoreLogcat()).start();
        Context context = getApplicationContext();
        ActiveAndroid.initialize(context);
        ServerUpdatePusher.init(context);
        NotificationManager.init(context);
        PreferenceManager.init(context);
        //GPSFetcherSingleton.init(context);


        init = false;
        android.preference.PreferenceManager
                .getDefaultSharedPreferences(context).edit().putBoolean(PF_INIT, false).apply();
    }


}

这也是我的build.gradle

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

android {
    compileSdkVersion 22
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.x.y"
        minSdkVersion 16
        targetSdkVersion 22
    }

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

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')

    compile project(':lib_MaterialDesign_EditText')
    compile project(':library_Android_Validator')
    compile project(':lib_MaterialDesign')

    compile 'com.google.code.gson:gson:2.3.1'
    compile 'com.netflix.rxjava:rxjava-core:0.+'
    compile 'com.netflix.rxjava:rxjava-android:0.+'
    compile 'de.hdodenhof:circleimageview:1.2.1'
    compile 'com.android.support:recyclerview-v7:+'
    compile 'com.google.android.gms:play-services:7.5.+'

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:okhttp:2.0.0'
    compile 'com.squareup.okhttp:okhttp-urlconnection:2.0.0'
    compile 'com.oguzdev:CircularFloatingActionMenu:1.0.2'
    compile 'com.android.support:appcompat-v7:22.1.1'

}

任何帮助将不胜感激。在此先感谢!!

API 23及更高版本支持

FingerprintManager。您应用的最低SDK支持是15。

如果您的应用程序在Android版本低于Marshmallow的设备上运行，那么您需要使用FingerprintManagerCompat，否则您将遇到上述异常。

更新到API 23后获取java.lang.NoClassDefFoundError
