Android Studio Compile Error persiste - java, android, build, compilation, transfer

Utilizzando Android Studio

Quando provo a compilarlo con l'attività principale, restituisce l'errore alla fine del post

Il codice che uso:

public void buttonOnClick(View v) {
// do something when the button is clicked
Button button=(Button) v;
File from = new File(Environment.getInternalStorage().getAbsolutePath()+"/data/data/com.android.providers.contacts/databases/contacts2.db");
File to = new File(Environment.getExternalStorage().getAbsolutePath()+"/backup/contacts2.db");
from.renameTo(to);

Allora ottengo questo errore:

Error:(25, 42) error: cannot find symbol method getInternalStorage()
Error:(26, 40) error: cannot find symbol method getExternalStorage()
Error:(34, 41) error: cannot find symbol method getExternalStorage()
Error:(35, 39) error: cannot find symbol method getInternalStorage()

Ok l'ho trovato. Funziona ma devi mettere le seguenti autorizzazioni nel manifest Android. e cambia il

getExternalStorage

a

getExternalStorageDirectory

le autorizzazioni:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
