Question

我的应用程序具有以下参数：

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "de.munich.myApp"
        minSdkVersion 17
        targetSdkVersion 23
        multiDexEnabled true
    }

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

我收录了支持包v7：

dependencies {
    compile 'com.google.code.gson:gson:2.4'
    compile 'com.android.support:appcompat-v7:23.2.0'
    compile 'com.google.android.gms:play-services:8.4.0'
    compile 'com.android.support:design:23.2.0'
    compile 'com.android.support:recyclerview-v7:23.2.0'
    compile 'com.android.support:cardview-v7:23.2.0'
}

现在我尝试使用Android版本4.4.2（API级别19）在Galaxy Ace上启动我的应用程序，并且因为找不到android.support.v7引用的某些方法而得到很多错误：

Could not find method android.view.Window$Callback.onSearchRequested, referenced from method android.support.v7.internal.view.WindowCallbackWrapper.onSearchRequested
Could not find method android.view.Window$Callback.onWindowStartingActionMode, referenced from method android.support.v7.internal.view.WindowCallbackWrapper.onWindowStartingActionMode
Could not find method android.content.res.TypedArray.getChangingConfigurations, referenced from method android.support.v7.internal.widget.TintTypedArray.getChangingConfigurations
Could not find method android.content.res.TypedArray.getType, referenced from method android.support.v7.internal.widget.TintTypedArray.getType

当然应用程序崩溃。

有没有办法解决这些问题而无需增加minSdkVersion？

修改

import android.app.Notification;
import android.content.Context;
import android.support.v4.app.NotificationCompat;

public class HelperNotification {

    /**
     *
     * @param context
     * @param title
     * @param message
     * @return
     */
    public static NotificationCompat.Builder buildNotification(Context context, String title, String message) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);

        builder.setContentTitle(title);
        builder.setContentText(message);

        int defaults = 0;
        defaults = defaults | Notification.DEFAULT_LIGHTS;
        defaults = defaults | Notification.DEFAULT_VIBRATE;
        defaults = defaults | Notification.DEFAULT_SOUND;

        builder.setDefaults(defaults);

        return builder;
    }
}

我添加了一些mor日志输出。这是我在带有API 17的Samsung Galaxy S3上运行我的应用程序（我的最低要求API）。上周，在我将库从23.0更新到23.2之前，一切正常。现在好像他找不到我定义的一些类。

Answer 1

要回答关于问题标题的问题，您应该将Notification更改为NotificationCompat，即：

NotificationCompat.Builder。

常规Notification.Builder只有API {20}才有setLocal。

Answer 2

正如Simas所述，API {20}中添加了setLocalOnly，因此无法在20以下的API中直接使用。开发AppCompat库是为了使新方法与旧API兼容。您应该使用NotificationCompat.Builder作为Simas提到的。

因此，如果您想使用旧版本的最新API方法，则必须使用兼容性库。

Answer 3

我找到了解决方案。

问题与65K Methods Count有关。我做了链接中推荐的android，所以我能够在较旧的设备上再次安装该应用程序 API＆＃39; S

找不到方法android.app.Notification $ Builder.setLocalOnly
