安卓动态申请权限

1、在AndroidManifest.xml中添加权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wq.ndk_audio">
    <uses-permission android:name="android.permission.INTERNET" />

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


    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:requestLegacyExternalStorage="true"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

备注说明： 1、添加读写权限

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

2、在application中添加该句 android:requestLegacyExternalStorage="true"

2、代码中动态申请权限

 private void requestMyPermissions() {
       
        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.WRITE_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {
            //没有授权，编写申请权限代码
            ActivityCompat.requestPermissions(MainActivity.this, new String[]    {Manifest.permission.WRITE_EXTERNAL_STORAGE}, 100);
        } else {
            Log.d(TAG, "requestMyPermissions: 有写SD权限");
        }
        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.READ_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {
            //没有授权，编写申请权限代码
            ActivityCompat.requestPermissions(MainActivity.this, new String[]    {Manifest.permission.READ_EXTERNAL_STORAGE}, 100);
        } else {
            Log.d(TAG, "requestMyPermissions: 有读SD权限");
        }
    }
