Android 动态获取系统权限+调用外部应用读取本地文件(TBS+自定义)
一、获取动态权限
1.创建Android应用，在配置文件中添加临时访问文件权限
<!-- android 7.0临时赋予访问权限 android:name="android.support.v4.content.FileProvider" --> <provider android:name="androidx.core.content.FileProvider" android:authorities="com.example.build_input" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> </provider>
新建xml文件，配置name和path路径
<?xml version="1.0" encoding="utf-8"?> <paths> <!-- name随便起--> <external-path name="camera_photos" path="/" /> </paths>
2.配置系统需要用到的系统权限
<!-- 向SD卡写入数据权限 --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_SETTINGS" tools:ignore="ProtectedPermissions" />
3.编写申请动态权限方法，在onCreate()方法中调用
//申请权限 private boolean getPermission(Activity activity){ boolean rs=false; // 声明一个集合，在后面的代码中用来存储用户拒绝授权的权 List<String> permissionList = new ArrayList<>(); String[] permissions = new String[]{ Manifest.permission.READ_EXTERNAL_STORAGE,//读取内存卡 Manifest.permission.WRITE_EXTERNAL_STORAGE,//写入内存卡 // Manifest.permission.MOUNT_UNMOUNT_FILESYSTEMS,//允许挂载和反挂载文件系统可移动存储 // Manifest.permission.READ_PHONE_STATE,//读取手机状态和身份 /* Manifest.permission.ACCESS_WIFI_STATE,//获取使用Wi-Fi等WLAN无线网络 Manifest.permission.CHANGE_WIFI_STATE,//允许程序改变Wi-Fi连接状态 Manifest.permission.ACCESS_NETWORK_STATE,//允许程序访问有关GSM网络信息 Manifest.permission.CHANGE_NETWORK_STATE,//允许程序改变网络连接状态 Manifest.permission.INTERNET,//访问网络连接，可能产生GPRS流量 Manifest.permission.BLUETOOTH,//允许程序连接到已配对的蓝牙设备 Manifest.permission.CAMERA,//相机 Manifest.permission.WRITE_SETTINGS,//允许程序读取或写入系统设置*/ }; permissionList.clear(); for (int i = 0; i < permissions.length; i++) { if (ContextCompat.checkSelfPermission(activity, permissions[i]) != PackageManager.PERMISSION_GRANTED) { Log.e(TAG,"权限未允许："+permissions[i]+"...."); permissionList.add(permissions[i]); } } if (permissionList.isEmpty()) {//未授予的权限为空，表示都授予了 Log.e(TAG,"已经获取到了所有权限"); return true; } else {//请求权限方法 String[] spermissions = permissionList.toArray(new String[permissionList.size()]);//将List转为数组 ActivityCompat.requestPermissions(activity, spermissions, 1); } return rs; }
4.处理授权回调
@Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if(requestCode==1){ if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { boolean request_rs=true; for(int i=0;i<grantResults.length;i++){ if (grantResults[i] != PackageManager.PERMISSION_GRANTED) { request_rs=false; } } if(request_rs){ Log.e("软件获取权限结果：","获取软件权限成功"); init(); }else{ Toast.makeText(this, "您拒绝了软件应用权限，因此无法使用该软件！", Toast.LENGTH_LONG).show(); showDialogTipUserGoToAppSettting(); } } } }
若未获取的权限，则提醒用户手动开启权限
/** * 提示用户去应用设置界面手动开启权限 */ private void showDialogTipUserGoToAppSettting() { new AlertDialog.Builder(this) .setTitle("存储权限不可用") .setMessage("请在-应用设置-权限-中，允许应用使用存储权限来保存用户数据") .setPositiveButton("立即开启", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // 跳转到应用设置界面 goToAppSetting(); android.os.Process.killProcess(android.os.Process.myPid()); } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { android.os.Process.killProcess(android.os.Process.myPid()); } }).setCancelable(false).show(); } /** * 跳转到当前应用的设置界面 */ private void goToAppSetting() { Intent intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); Uri uri = Uri.fromParts("package", getPackageName(), null); intent.setData(uri); startActivityForResult(intent, 123); }
二、调用应用打开本地文件
第一种，根据文件类型自动选取应用打开文件
1.创建文件类型数组
/** * -- MIME 列表 -- */ public static final String[][] MIME_MapTable = { // --{后缀名， MIME类型} -- {".3gp", "video/3gpp"},{".3gpp", "video/3gpp"},{".aac", "audio/x-mpeg"}, {".amr", "audio/x-mpeg"},{".apk",

"application/x-compress"}, {".zac", "application/x-zaurus-zac"}, {".zip", "application/zip"}, {"", "*/*"} };
2.获取File文件路径，自定义打开文件
try { Intent intent = new Intent(); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setAction(Intent.ACTION_VIEW); //Uri.fromFile(new File()) 会出现乱码 intent.setDataAndType(Uri.parse(Uri.decode(url)), FilePath.getMIMEType(url); startActivity(intent); Intent.createChooser(intent, "请选择对应的软件打开该附件！"); } catch (ActivityNotFoundException e) { Toast.makeText(MainActivity.this, "附件打开失败，请下载相关软件！", Toast.LENGTH_SHORT).show(); } /** * --获取文件类型 -- */ public static String getMIMEType(String filePath) { String type = "*/*"; String fName = filePath; int dotIndex = fName.lastIndexOf("."); if (dotIndex < 0) { return type; } String end = fName.substring(dotIndex, fName.length()).toLowerCase(); if (end == "") { return type; } for (int i = 0; i < MIME_MapTable.length; i++) { if (end.equals(MIME_MapTable[i][0])) { type = MIME_MapTable[i][1]; } } return type; }
第二种，调用TBS服务打开文件
1.引入jar包或gradle
//引入腾讯x5 服务 implementation 'com.tencent.tbs.tbssdk:sdk:43939'
2.初始化TBS、调用方法打开文件
// 在调用TBS初始化、创建WebView之前进行如下配置 HashMap map = new HashMap(); map.put(TbsCoreSettings.TBS_SETTINGS_USE_SPEEDY_CLASSLOADER, true); map.put(TbsCoreSettings.TBS_SETTINGS_USE_DEXLOADER_SERVICE, true); QbSdk.initTbsSettings(map); QbSdk.openFileReader(MainActivity.this, finalResultData.get(position).getUrl(), null, new ValueCallback<String>() { @Override public void onReceiveValue(String s) { // Toast.makeText(getApplicationContext(),s,Toast.LENGTH_SHORT).show(); } });
