Android10动态申请读写权限

1、在中添加权限

<?xmlversion="1.0"encoding="utf-8"?>

package="_audio">

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">

备注说明：

1、添加读写权限

2、在application中添加该句

android:requestLegacyExternalStorage="true"

2、代码中动态申请权限

privatevoidrequestMyPermissions(){

if(elfPermission(this,

_EXTERNAL_STORAGE)

!=SION_GRANTED){

//没有授权，编写申请权限代码

tPermissions(,newString[]{_EXTERNAL_STORAGE},100);

}else{

Log.d(TAG,"requestMyPermissions:有写SD权限");

}

if(elfPermission(this,

_EXTERNAL_STORAGE)

!=SION_GRANTED){

//没有授权，编写申请权限代码

tPermissions(,newString[]{_EXTERNAL_STORAGE},100);

}else{

Log.d(TAG,"requestMyPermissions:有读SD权限");

}

}
