3.5.0通知栏显示Icon：https://github.com/WVector/AppUpdate
用两种方式实现了更新的效果，项目结构如下：
5.0通知栏不显示icon的解决方式：
/** * 初始化通知栏 */ private void initNotify() { mNotifyManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); mBuilder = new NotificationCompat.Builder(this); mBuilder.setContentTitle(String.format("%s V%s", getString(getApplicationInfo().labelRes), mVersionName)) //通知首次出现在通知栏，带上升动画效果的 .setTicker("捷账宝新版本诚邀体验") //通常是用来表示一个后台任务 .setOngoing(true) //通知产生的时间，会在通知信息里显示，一般是系统获取到的时间 .setWhen(System.currentTimeMillis()); //解决5.0系统通知栏白色Icon的问题 Drawable appIcon = getAppIcon(this); Bitmap drawableToBitmap = null; if (appIcon != null) { drawableToBitmap = drawableToBitmap(appIcon); } if (drawableToBitmap != null) { mBuilder.setSmallIcon(R.mipmap.app_update_icon); mBuilder.setLargeIcon(drawableToBitmap); } else { mBuilder.setSmallIcon(getApplicationInfo().icon); } } /** * 合成更新的Icon * * @param drawable * @return */ public Bitmap drawableToBitmap(Drawable drawable) { Bitmap bitmap = Bitmap.createBitmap( drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), drawable.getOpacity() != PixelFormat.OPAQUE ? Bitmap.Config.ARGB_8888 : Bitmap.Config.RGB_565); Canvas canvas = new Canvas(bitmap); drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight()); drawable.draw(canvas); return bitmap; } /** * 获取App的Icon * * @param context * @return */ public Drawable getAppIcon(Context context) { try { return context.getPackageManager().getApplicationIcon(context.getPackageName()); } catch (PackageManager.NameNotFoundException e) { e.printStackTrace(); } return null; }7.0文件读取的解决方式：
1.配置文件增加provider <!--authorities：app的包名.fileProvider （fileProvider可以随便写）,上面采用的是gradle的替换直接写成包名也可以，但是推荐这种方式，多渠道分包的时候不用关心了--> <!--grantUriPermissions：必须是true，表示授予 URI 临时访问权限--> <!--exported：必须是false--> <provider android:name="android.support.v4.content.FileProvider" android:authorities="${applicationId}.fileProvider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths"/> </provider>2.在res新建xml文件件，然后新建provider_paths.xml,copy如下代码: <?xml version="1.0" encoding="utf-8"?> <paths xmlns:android="http://schemas.android.com/apk/res/android"> <!--external-path中，--> <!--name：可以随意写，只是一个名字--> <!--path：表示文件路径，.表示所有--> <external-path name="external_files" path="."/> </paths>3.启动安装界面的时候 /** * 启动安装界面 * * @return */ private Intent getInstallIntent() { File apkInstallDir = FileManager.getApkInstallDir(getApplicationContext()); Log.i("TEST", "路径---" + apkInstallDir.getAbsolutePath()); Intent intent = new Intent(Intent.ACTION_VIEW); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) { intent.setDataAndType(Uri.fromFile(apkInstallDir), "application/vnd.android.package-archive"); } else { // 声明需要的零时权限 intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // 第二个参数，即第一步中配置的authorities Uri contentUri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".fileProvider", apkInstallDir); intent.setDataAndType(contentUri, "application/vnd.android.package-archive"); } return intent; }methone：第一种方式是用IntentService实现的，这种方式的好处是，下载完后，通知栏自动移除，服务自动销毁
/** * @author zhouhui */public class DownloadIntentService extends IntentService { /** * 默认超时时间 */ private static final int DEFAULT_TIME_OUT = 10 * 1000; /** * 缓存大小 */ private static final int BUFFER_SIZE = 10 * 1024; public static final String INTENT_VERSION_NAME = "service.intent.version_name"; public static final String INTENT_DOWNLOAD_URL = "service.intent.download_url"; public static final String SAVE_FILE_NAME = "CMPP.apk"; private static final int NOTIFICATION_ID = UUID.randomUUID().hashCode(); private String mDownloadUrl; private String mVersionName; private NotificationManager mNotifyManager; private NotificationCompat.Builder mBuilder; public DownloadIntentService() { super("DownloadService"); } /** * Creates an IntentService.
