/**     * 安裝apk     *     * @param context     * @param apkPath     */    public static void installApk(Context context, String apkPath) {        try {            /**             * provider             * 處理android 7.0 及以上系統安裝異常問題             */            File file = new File(apkPath);            Intent install = new Intent();            install.setAction(Intent.ACTION_VIEW);            install.addCategory(Intent.CATEGORY_DEFAULT);            install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {                Uri apkUri = FileProvider.getUriForFile(context, "com.jxzg.jxzgapp.fileprovider", file);//在AndroidManifest中的android:authorities值                Log.d("======", "apkUri=" + apkUri);                install.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);//添加這一句表示對目標應用臨時授權該Uri所代表的檔案                install.setDataAndType(apkUri, "application/vnd.android.package-archive");            } else {                install.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");            }            context.startActivity(install);        } catch (Exception e) {            Log.d("======", e.getMessage());            Toast.makeText(context, "檔案解析失敗", Toast.LENGTH_SHORT).show();            deleteFile(apkPath);        }    }

androidManifest.xml 裡面註冊provider

<provider        android:name="android.support.v4.content.FileProvider"        android:authorities="com.chao.app.fileprovider"        android:grantUriPermissions="true"        android:exported="false">        <meta-data            android:name="android.support.FILE_PROVIDER_PATHS"            android:resource="@xml/file_paths" /> </provider>

需要添加許可權

<uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES" />

在/res/xml/下建立 file_paths.xml

<?xml version="1.0" encoding="utf-8"?><resources>    <paths>        <external-path path="" name="download" />    </paths></resources>
