平台
RK3288/RK3368 + Android 7.12
问题
在旧的SDK上, 可以通过设置默认 ro.rk.install_non_market_apps=true, 默认打开安装未知来源应用 在新的代码上此属性不生效
解决

插曲
刚开始加的代码是:
loadBooleanSetting(stmt, Settings.Secure.INSTALL_NON_MARKET_APPS, R.bool.def_install_non_market_apps); String propNonMarket = android.os.SystemProperties.get("ro.rk.install_non_market_apps"); if(propNonMarket.equals("true")){ loadSetting(stmt, Settings.Secure.INSTALL_NON_MARKET_APPS, "1"); }
这是无效的, 原因是, 第一行的代码已经往数据库里插入了数据. 见下面SQLiteStatement 的赋值方式:
SQLiteStatement stmt = null; stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)" + " VALUES(?,?);");
