Android 10动态申请读写权限

1、在中添加权限

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:andro
    package=".ndk_audio">
    <uses-permission android:name="" />

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

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

</manifest>
备注说明：
1、添加读写权限
<uses-permission android:name=".WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name=".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 ((this,
                .WRITE_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {
            //没有授权，编写申请权限代码
            (, new String[]{.WRITE_EXTERNAL_STORAGE}, 100);
        } else {
            (TAG, "requestMyPermissions: 有写SD权限");
        }
        if ((this,
                .READ_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {
            //没有授权，编写申请权限代码
            (, new String[]{.READ_EXTERNAL_STORAGE}, 100);
        } else {
            (TAG, "requestMyPermissions: 有读SD权限");
        }
    }
